Biophysics, and Cell Respiration
Sian Hall What is biophysics?
To answer this question we first must explore biology, and what exactly it entails. Biology is the study of living organisms, with many different, interacting fields. Biology is an important branch of science, as it is essentially the study of life in the world around us. Without biology we would not be able to examine the growth, structure, origin, function, evolution or distribution of living things. Four principles form the basis of biology; cell theory, evolution, genetics, and homoeostasis. Physics, on the other hand, is the branch of science that explores the nature and properties of energy and matter, including mechanics, heat, light and other radiation, electricity, …show more content…
Most simply, cells function only to grow, replicate, and divide. In order for cells to do this, they need energy, which comes from the food consumed by the main organism. All food contains energy, measured in kilojoules. The food we consume is turned into glucose by the body, and used to power every cell, in every part of our bodies. This chain of processes is called cellular respiration. This is the process in which glucose, combined with oxygen and water is turned into water and carbon dioxide, expressed in the …show more content…
The inside of a cell has a composition, and this construction is not static. Additionally, cells must live in and interact with the surroundings, which is often unforeseeable and not always approbatory. In order to grow, move, and survive, cells must be able to convert force. That is, physics matters, at least at some level. Physics enables biologists to be able to better predict the movement of cells, and why this movement occurs in the patterns that it does. Physicists detailed knowledge of forces assists biologists, and in this case cell biologists, with hypothesising the reasons behind the function of complex processes within the human

Cellular Respiration In Stem Cell Research

...The cause of cancer relates to the process known as cellular respiration. Cellular respiration is a four step process that ultimately oxidizes glucose into ATP. The first step occurs in the cytoplasm and is called glycolysis. This stage is where glucose is broken down into pyruvate and two ATP. This pyruvate moves into the mitochondrial matrix where it is further oxidized into acetyl CoA before moving into the citric acid cycle to become NADH and FADH2. The final step occurs in the inner membrane space and is known as the electron transport chain. NADH and FADH2 donate electrons which will be shuttled between the complexes. Once the fourth complex is powered, the electron is released and accepted by oxygen. The proton motor force powers the ATP synthase by forcing hydrogen to flow through it allowing approximately 32 ATP to be synthesized....

Energy, Metabolism, and Cells – Photosynthesis & Cellular Respiration

...Science 206 Energy, Metabolism, and Cells – Photosynthesis & Cellular Respiration John Carter August 11, 2013 1. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. Photosynthesis can be defined as the process that living organisms such as plants use to translate the sun’s energy into chemical energy. Once the plant has translated the sun’s energy into chemical energy it then releases that energy and makes it readily available to other living things (Vermaas, 2007). Aerobic respiration can be defined as nutrients being converted into useful energy. Respiration allows cells to use the energy stored during the photosynthesis process. It’s the chemical reaction that breaks down the glucose and changes it into a larger amount of Adenosine Triphosphate which is also called ATP (Board, 2012). Plants use sunlight to make ATP for its energy source by creating a series of chemical reactions by producing oxygen as a waste product. Next, animals and human beings eat these plants. The nutrients digested by animals and human beings reverse the process by using the ATP as a source of energy. Our cells use the nutrients from the plants and convert the nutrients in a process that uses oxygen (Board, 2012). Once our bodies have used all the nutrients will be need from those plants our bodies as well as animals release carbon dioxide as waste. Photosynthesis and respiration are both means of converting one state...

...System 96 • Activity 2: Measuring Respiration . . . 96 • Activity 3: Film: “Deadly Ascent” . . . 100 [pic] Introduction The organs of the respiratory system include the nose, nasal cavity, sinuses, pharynx, larynx, trachea, respiratory tree, and lungs. They function to transport air to the air sacs of the lungs (the alveoli) where gas exchange occurs. The process of transporting and exchanging gases between the atmosphere and the body cells is respiration. The process of taking in air is known as inspiration, while the process of blowing out air is called expiration. A respiratory cycle consists of one inspiration and one expiration. The point of respiration is to allow you to obtain oxygen, eliminate carbon dioxide, and regulate the blood’s pH level. Respiration rate (breaths per minute) and depth (volume of air inhaled and exhaled with each breath) varies due to changes in blood chemistry that are monitored by the brain. For example, when you exercise, demand for oxygen increases because the cells require more ATP. In turn, more carbon dioxide is produced by cells and diffuses to the blood. The rise in carbon dioxide leads to a decrease in pH, causing the blood to be more acidic. The brain is especially sensitive to pH levels; as pH levels in the blood fall, the brain stimulates more rapid breathing and deeper breathing. The effect is to draw more air into the lungs, to transport more oxygen to the cells, and lower pH and CO2 levels. Check...

...This gaseous exchange is called respiration. Respiration can be defined as process by which living beings obtain oxygen to oxidize their reserve digested food in order to release energy. The organs which help in intake or supply of oxygen to the tissues and remove excess Co2 form respiratory system. Breathing in frogs are of three types: 1. Cutaneous respiration (Respiration through skin) 2. Respiration through lining of bucco-pharyngeal cavity 3. Pulmonary respiration (Respiration through lungs) 1) Cutaneous respiration: It is an important mode of respiration in frog which occurs all the time whether the frog is on land or in water. It is the only mode of respiration when the frog in dormancy period, i.e during hibernation and aestivation. The skin of frog has good supply of blood and this is provided by cutaneous artery. Moreover the skin is very thin and do not possesses any structure that may prevent the diffusion of the dissolved oxygen from water into blood. To carry on cutaneous respiration frog keeps its skin moist by taking occasional plunges into nearby water. The skin is also kept moist by mucus secreted by mucous glands of skin. Mechanism: Oxygen first dissolves in the film of water over the skin and then passes through the epidermal cells and capillary walls into the blood. On the other hand carbon dioxide passes out from blood into the water. 2) Respiration through lining of bucco-pharyngeal cavity: In buccal respiration on land, the mouth remains permanently...

The Respiratory System

...speaking, and your sense of smell. External respiration better known as as breathing, is the process by which air from the environment is taken into the body, that oxygen is then supplied to the lungs, then waste carbon dioxide in expelled from the body(Internal and External Respiration). Once inside the lungs, oxygen is then transferred to the blood stream and cells this is called internal respiration. This exchange is probably one of the most crucial functions in the body. In a process called diffusion incoming oxygen moves to lower concentrations in the blood stream while at the same time waste carbon dioxide is moved to lower concentration of carbon dioxide outside the body. The same happens when the blood stream reaches cells, diffusion causes one more gas exchange before the cycle can repeat itself close to another eleven times that many minute(Breathing and the Human Respiratory System). When a person begins to speak, they may not realize it, but they are using the respiratory system to execute this function. When air is exhaled it travels down your windpipe and through your voice box. When the air passes through sound is emitted and manipulated by the mouth to produce speech(Language Bits). Olfaction, or the body's ability to smell is a very important one. This characteristic is a vital sense for humans and is used to identify many smells we encounter. Humans are able to smell when air is inhaled through external respiration through the nose and into the sinuses. The sinuses...

Explain The Physiology Of Two Named Body Systems In Relation To Energy Metabolism

... The lung is the main organ which the lungs intakes oxygen into the body and the carbon dioxide is exported out. The respiration system is made up of many organs which help us to breathe properly. The digestive system is where the organs inside the body break down the food and convert it to energy and nutrients that are needed in the body. The stomach is a tube shaped which has all the food and liquid that we have ate and it makes around the body and it is a mainly long twisted tube that starts from the mouth and comes all the way down to the anus and into few organs such as the pancreas and the liver which stores any chemicals accessible. The metabolic rate...

How Does Tuberculosis Affect The Respiratory System?

...The respiratory system is an organ system which provides oxygen for the body and allows carbon dioxide leave the body; also known as breathing. There are four processes involved with respiration: ventilation of the lungs, gas exchange between air and blood in the lungs, gas transport in the blood, as well as gas exchange between the blood and target tissues. The respiratory consists of the nasal cavity which warms, cleans, and humidifies inhaled air, and the pharynx which is where the respiratory and digestive systems meet and split again. The larynx contains the vocal cords, and the trachea is a tube that passes behind the heart. The bronchi and bronchioles are air tubes that begin at the fork of the trachea and divide into smaller tubes into each lung, and the alveoli are millions of miniscule sacs of air in the lungs. The respiratory system is imperative for every breathing being’s survival. However, there are many impairments that can occur in this organ system, in both infectious and uncommunicable...

Daily Goal: Practice the correct breathe way and try to find a balanced, free, and flexible singing posture as Emily said in the class, and also do some warm up. In the first voice class, I learnt that how to breathe in a right way. I not only need to inhale quickly and exhale slowly when I sing a song, but I also need to maintain right posture. Emily taught me that when I inhaling or exhaling, I both need to release my shoulder and muscle. When I practice the inhaling, I try to only to mouth to inhale. I also practice to explore the sensation that let the air fall lower than my belly button. Then let the breath fall in faster. After that I felt that my abdomen and lower back expand. When I practice the exhaling, I felt that it is more difficult to expand my belly than inhaling. I have to control my exhalation and have a sustained and smooth exhalation.

...Pre-oxygenation in the obese patient: effects of position on tolerance to apnoea ------------------------------------------------- ------------------------------------------------- Abstract Background. In obese patients, reduced functional residual capacity exacerbated by supine position might decrease the effectiveness of pre-oxygenation and the tolerance to apnoea. The aim of this study was to compare the effect of body posture during pre-oxygenation, sitting or supine, on its effectiveness in obese patients. Methods. Forty obese patients (BMI ≥35 kg m−2) undergoing surgery with general anesthesia were randomly assigned to one of two groups: Group 1 (sitting, n=20) or Group 2 (supine, n=20). In the predetermined body position, pre-oxygenation was achieved with eight deep breaths within 60 s and an oxygen flow of 10 litre min−1. After rapid sequence induction of anesthesia in decubitus position, the trachea was intubated and the patient was left apneic and disconnected from the anesthesia circuit until SpO2 decreased to 90%. The time taken for desaturation to 90% from the end of induction of anesthesia was recorded. Arterial blood oxygen tension was measured before (baseline) and after pre-oxygenation. Values were compared with two-way ANOVA and unpaired Student's t-test. Results. Oxygen and carbon dioxide tensions were similar between groups, both at baseline and after pre-oxygenation. However, the mean time to desaturation to 90% was significantly longer in the sitting group...

Hemoglobin Research Paper

...In order to sustain life, one important function humans must do is breathe. We breathe in oxygen and breathe out carbon dioxide. Once the oxygen is in the body, it must then be transported throughout the body. Oxygen has a non-polar polarity which allows it to cross the non-polar membrane of cells easily. However, oxygen will need help to move in the body and it is iron that will be moving oxygen around in the body. Within the red blood cells of the body, there is the component of hemoglobin that is used to transport oxygen and with iron, the production of hemoglobin is made possible. To begin, iron will be taken in and absorbed by the body through consumed foods. The absorption of iron takes place in the middle part of the small intestines,...

Resting Metabolic Rates

...Intro: Due to the variation in resting metabolic rates seen in different species, scientist have considered the relationship between body mass and metabolic rates and what effect that has on each specimen on a biological level. The respiratory system’s main function is gas exchange as oxygen enters the lunges and travels to the alveoli for most reptiles and mammals. Insects however, do not have a gas transport system, leading to air traveling directly to the tissues carrying out respiration. The energy expenditure is directly linked to gas exchange in both humans and animals. Indirect calorimetry is used to determine the total metabolic rate by measuring both CO2 production and O2 consumption. Insects use spiracles, valve openings along the cuticle, in order to...

Asthma Research Paper

...Did you know that breathing exercises could work as alternative asthma treatments? Several exercises were found to be effective in reducing the symptoms of asthma and it could also contribute to a lower dose of medication. What is asthma in the first place? Asthma is a chronic lung condition that causes difficulty in breathing. When left untreated, asthma can be fatal. It is important for asthma to be properly diagnosed by a doctor and its treatment needs to be supervised. Medications like bronchodilators are often given to asthma patients to relieve symptoms such as wheezing, chest pain, and shortness of breath but natural alternative asthma treatments can also be a big help. There are actually many alternative asthma treatments available. These include diet modification, acupuncture, breathing exercises, aromatherapy, vitamin and mineral supplementation, and herbal remedies. Breathing exercises are among the alternative asthma treatments that are considered both safe and effective. In asthma, patients experience difficulty in breathing. This exercises are aimed to relax the chest muscles and to teach the right way of breathing, focusing more on the abdomen and the diaphragm rather than on the muscles of the chest. It also helps asthma patients focus more on breathing out or exhalation especially at the onset of an attack. Here are three examples of breathing exercises that may be used by asthmatic patients. -PRANAYAMA Pranayama refers to the breathing exercises used during...
