One molecule of CP produces one ATP. 6. Glucose is a major source of energy for synthesizing ATP. List the two sources of glucose: 1. Glucose enters the muscle cell directly from the blood. 2. Glucose is produced by hydrolysis of glycogen stored in the muscle cell. 7. Glycolysis is the process that breaks down glucose. Name two products of the breakdown of glucose: 1. Two ATP molecules 2. Pyruvic acid If oxygen is not available‚ pyruvic acid is

Case 1: Hereditary fructose intolerance Enzymes are proteins that increase the rate of chemical activity. Their three dimensional structure determines their function‚ and is made of chains of amino acids that have folded into a specific shape with a unique property. Enzymes lower the activation energy needed for a chemical reaction‚ therefore speeding up the process. Multiple enzymes work together in metabolic pathways‚ taking a product (end result) of one metabolic reaction as a substrate (substance

Homeostasis The conditions inside our body must be very carefully controlled if the body is to function effectively. Homeostasis is the maintenance of a constant internal environment. The nervous system and hormones are responsible for this. One example of homeostasis is the concentration of carbon dioxide in the blood being carefully controlled. Here are some of the other internal conditions that are regulated: Body temperature This is controlled to maintain the temperature at which the

THE GREAT METABOLIC RACE INTRODUCTION During exercise‚ carbohydrates and lipids are required in order to provide energy for the working body. The inherent reduced nature of these compounds allows for partial or complete oxidation in extracting energy in the form of adenosine triphosphate (ATP). The varying chemical structure of the macromolecules evokes different processes for their complete utilisation. This paper seeks to expound on the mobilisation of these fuels‚ the biochemical pathways that

Introduction: In Musculoskeletal system‚ during large amounts of physical activity the muscle will encounter fatigue‚ as a result of depletion of muscle glycogen or because of interruption of blood flow during contractions of the muscle as well the lack of oxygenation it provides to the muscles. To test this theory we will compare the time it take for the index finger and the muscles around it to reach fatigue after a variation of excises. We will compare these results in Mann (2014) to see how

Muscle building quickly is one goal a lot of body builders try to work hard on. As much as they also go for definition‚ shape and symmetry‚ these things are usually secondary for the goal of building muscle mass‚ at least for serious body builders. Most‚ if not all of them‚ adhere to the belief that having muscle mass is what separates a truly spectacular physique from the average person who just wants to flaunt an aesthetically nice and toned body. The first tip that people should take notice

Its main function is as a storage carbohydrate‚ starch and glycogen are suitable for this function because there are insoluble and compact. 5.
