would have more type II fibers‚ since their training involves more strength exercises (Kenney‚ 2011‚ p. 46). 2. Describe the mechanisms by which muscle glycogen is broken down to glucose for use in glycolysis. Glucose is converted to glycogen in order to be stored in the liver and muscles to use at a later time. When the body is ready to use these glycogen stores for

good sugars and 400 become bad sugars during the digestion. These 500 sugars mix in the blood. Let us assume that there is no stored glycogen available in his body. What will happen now? The 100 good sugars will get insulin and enter into the cells. The 400 bad sugars will not get insulin and go out through the urine. Adrenal gland will search for glycogen. Since glycogen is not available‚ it will not be able to supply sufficient glucose to the cells. Since sufficient sugar is not supplied‚ the cells

Muscles contain large storages of complex carbohydrates called glycogens. Glycogens are the stored form of sugar found in our bodies. Through a complex series of chemical reactions glycogen breaks down into ATP as well as lactic acid. This system supplies ATP slower than the Phosphocreatine system. The body cannot produce enough ATP to maintain this energy source for longer

INTRODUCTION Macromolecules are highly important organized organic molecules that are found within living cells. These biological molecules help the body execute precise important tasks. There are four types of macromolecules: carbohydrates‚ lipids‚ proteins and nucleic acids. (Karp‚ 2010) This specific experiment showcased the identification of different macromolecules using three different testing methods. Carbohydrates‚ sugar molecules‚ are known as “fast fuel” in the body‚ and they contain

the lactic acid system will continue providing ATP molecules to create required energy. This system produces lactic acid as a waste product in the chemical breakdown of glucose and glycogen (glycolysis). After lactic acid system has used all PC‚ body needs to find a new fuel in the form of blood glucose or glycogen stored in the muscle to keep going. Lactic acid then builds up in the cell and is transferred into the blood stream where the body tries to get rid of. Requires oxygen to make the

Insulin will stimulate liver to store excess glucose as glycogen and also fatty acid which stored in adipose tissue. It activates the enzyme hexokinase‚ which phosphorylates glucose‚ trapping it within the cell and hence block the activity of glucose-6-phosphatase (Plum‚ Belgardt & Brüning 2006). Insulin will restrain fuel mobilization and breakdown of glycogen are blocked. Hence‚ causes the glucose to decrease gradually. However‚ the blood glucose will go
