Lab Report

After adding the Flavin mononucleotide to the chloroplasts, it made the voltages go up by 5 millivolts.

When the light bulb got turned on, it causes the cells to have more energy, and that way it made more volts.

Once the sodium bicarbonate was added into the chamber, it caused even more millivolts, while the light stayed on.

Once the light bulb was turned off, it slowed the cells back down and didn’t cause as many volts.

The millivolts only went up a little bit.

The millivolts went up a lot more than just adding the methylene blue to it

The voltage went up a little bit more than the glucose made the volts go up

When the light bulb was turned on, it created more voltages inside the chamber, it caused the cells to gain energy

The sodium bicarbonate was added to the chamber, and it didn’t make too much of a difference, it went up to 10 millivolts.

Nutrition Lab #1

...NUTRITION 121 HUMAN NUTRITION LABORATORY BACKGROUND AND METHODS MODULE #1 BODY COMPOSITION Late Labs: 10 point deduction! A report submitted >1 week late, will receive 0 points for the lab!! Written and edited by: Karon Felten and Nutrition 121 TA’s With Special Thanks to: Chris Pritsos Ph.D. Nutrition Department Chairman ABSTRACT: In nutrition, there are many factors that influence an individual’s health and body weight, such as heredity, food selection, eating behaviors, and physical activity. Scale weight is not always a good indicator of body fat, lean mass, body water or overall health (1). This laboratory experience will give students the opportunity to conduct physical assessments by evaluating body weight and body composition. To determine body weight and body composition, techniques such as bioelectrical impedance analysis (BIA), body mass index (BMI), waist circumference, wrist circumference for determining frame size, and a scale will be utilized. Students will also evaluate their own risk for cardiovascular disease and assess cardiovascular health in volunteers by measuring heart rate, filling out a heart disease risk score form, and estimating oxygen consumption and energy expenditure through a technique known as the Queens College Three-Minute Step Test. BACKGROUND: Your body is made up of the six essential nutrients: water, fat, protein, carbohydrates and various vitamins and minerals. Many factors can influence an individual’s...

Cells

...Cell Structure and Function AbstractThis report is about cell structure and function. The cell is the basic unit of life. All living things are madeof cells. By doing this lab, I hoped to learn how a cell looked and how it functioned. I also wanted toknow the differences between prokaryotic cells and eukaryotic cells Introduction The concept of this lab is producing a replica of an animal cell, and a plant cell. Producing the models of the cells helps to provide a better understanding of each cell and its contents also, to explore thedifferences between prokaryotes and eukaryotes. Cell theory states that all cells reproduce new cells,while passing their genetic information. In addition, cells make up all living things, metabolize energyand that the chemical make-up of cells is similar. The objectives for this lab are to gather the materials,which include gelatin packs, plastic bags, water, Tupperware, bowls, and some small various householditems. The other objectives are preparing the gelatin as directed, gathering the household items that willserve as cell organelles, pouring the gelatin in the bag and placing the items in the plastic bags. Thenplace the cell replicas in the refrigerator for 24 hours. Results After twenty-four hours, I removed the cell replicas from the refrigerator and observed them. They didnot look exactly like I planed but they were understandable. Discussion Replicating the cell structures provides better understand the structure and...

Cellular Respiration

...Cellular Respiration Lab Report Purpose The purpose of this lab was to find out which substance, molasses, sucrose, or the items of choice. This experiment was done to help the students understand which substance the yeast could perform cellular respiration in and why it could depending on it’s structure and bonds. From this experiment students should be able to better understand cellular respiration and why it occurs, like how it happens and how the organism benefits from cellular respiration. Also it should be understood what substances cellular respiration occurs on more easily and which substances take longer, and why that is because of what they are composed of. Hypotheses For this experiment there were two substances to be brought in and experimented with, substances that were tried were pure honey and water. 1). 50 ml of pure honey will produce 10 cm of carbon dioxide. 2). 25 ml of pure honey diluted with 25 ml of water will produce 7 cm of carbon dioxide. Introduction There are two processes to remove energy, that is aerobic and anaerobic. Anaerobic is the process of fermentation and requires no oxygen. Aerobic is cellular respiration and requires oxygen. Going further into aerobic is the process of cellular respiration is the process which energy is removed in the form of ATP, this process requires oxygen and a food source. All Oxygen using organisms perform cellular respiration. There are 3 major steps to cellular respiration: 1). Glycolysis- It...

...Jamie Morris Biology 101 Dr. Siddiqui April 13, 2016 Cellular Respiration Lab Report Cells can’t grow, reproduce, maintain order or transport materials without a steady source of energy. In most organisms, the energy is provided by adenosine triphosphate (ATP). In order to for these cells to reach their energy demands they must constantly produce ATP. In this lab, we will observe evidence for respiration in mealworms and investigate the effects of different temperatures and experimental variables such as caffeine, nicotine and DEET. The background information includes using nicotine and caffeine, which act lie insecticides. It also found in the soil of these plants. In humans it not only stimulants the central nervous system but increases our heart rate, blood pressure and makes us more alert. Ethanol comes from plants sugars and found in beer, wine and liquor. When humans drink too much they become impaired and their thought process in slowed down. Temperature is also an important factor for all living things environment. Improper temperature can affect interactions between enzyme and its substrate. DEET is a topical insect repellent. It locks insect’s sense of smell.
