Unit 3. Assignment 1: Bacterial Growth Rates 1. Mediums that could be used to determine shigellosis include Btilliant Green Agar, and Triple Sugar-Iron Agar. Expected results in a confirmed case of shigellosis are as follows: Brilliant Green Agar – Isolated Shigella colonies which do not ferment lactose or sucrose and appear red or white in color with no growth to trace growth on the Agar plate will be present. Triple Sugar-Iron Agar – Presence of Shigella will manifest as a red slant

Yeast Culture Lab BIO/315 April 22, 2014 Annissa Furr Yeast Lab Yeast, is a microscopic one celled organism that belongs to the group of organisms that is called fungi. They are single celled organisms that have a scientific name of Saccharomyces cerevisiae. Yeast can have many purposes but the main purpose of yeast is to help the fermentation process. Yeast is a living organism known as a fungus and it gets its energy source from sugar. Yeast can also be used in creating certain medical

within every living cell or organism, it is sum of all chemical processes that happen within the cell. By definition there are many kinds of metabolisms aerobic respiration, anaerobic respiration and fermentation. Aerobic respiration is the process of breakdown of glucose to produce ATP, which requires presence of Oxygen. Aerobic respiration involves four steps glycolysis, formation of acetyl coenzyme A, the citric acid cycle and electron transport chain. Two enzymes that indicate the presence of electron

1. ATP can be produced by two types of phosphorylation. Once a glucose molecule has been admitted into a hepatic cell, describe how ATP can be produced using each type of phosphorylation. Describe the general chemistry of how each type of energy production occurs. Be sure to give a complete explanation of how glucose metabolism results in ATP production (hint: electron carriers are not the same as ATP). (16 points) ATP plays an essential role when it comes to the production of energy in the body

carbohydrates; thus glucose is a basic energy source for all living organisms. The oxygen released, with water vapor in transpiration, as a photosynthetic byproduct, principally of phytoplankton, provides most of the atmospheric oxygen vital to respiration in plants and animals, and animals in turn produce carbon dioxide necessary to plants. Photosynthesis can therefore be considered the ultimate source of life for nearly all plants and animals by providing the source of energy that drives all their

Krebs cycle is the second pathway of aerobic respiration. The Krebs cycle alludes to a perplexing arrangement of chemical reactions that deliver carbon dioxide and ATP, a compound high in energy. This cycle happens by essentially connecting 2 carbon coenzyme with carbon compounds in the cell. This created compound then experiences a progression of changes that produce energy. This cycle happens in all cells that use oxygen as a component of respiration. Carbon dioxide is important in the Krebs cycle

digestive system. The respiratory system is where the exchange of gases in the body this is where the oxygen enters into the blood. 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

Design Lab: Respiration The Effect of Heavy-Duty Exercise on the respiration of Homo Sapiens (Humans) Research Question: What is the effect of heavy-duty exercise (cardiovascular and other activities) on the respiration of humans? Background Information: In this experiment, trials will be conducted consisting of humans run up a set of stairs up and down 3 times as fast as they possibly can in order to put pressure on oxygen need to increase respiration needs. This will test the effect of

Mantra Breathing Meditation Directions as Follows: 1. Sit comfortably on a straight-backed chair. 2. Place your hands in your lap, gently clasped or cupped. 3. Breathe in slowly and deeply through your nose. Feel your abdomen move outwards as your diaphragm contracts and draws air into your lungs. Your chest should not rise noticeably. 4. Hold your breath for 3-4 seconds... You may start off by counting to get into the proper, slow rhythm. 1-2-3-4... 5. Now sigh with relief

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
