Physiological Principles 5013SPOSCI: Coursework Assignment 1 Lab Report: Substrate use during high and low intensity exercise Introduction (20%) There are 3 distinct, yet closely integrated processes that work together interchangeably during exercise to fulfil the energy requirements of the muscle (Gastin, 2001). The primary role of these 3 processes - Phosphocreatine (PCr), Carbohydrate Oxidation (CHO) and Fat Oxidation (FOX)- is to resynthesize adenosine triphosphate (ATP) from adenosine…

Lipid Digestion: Absorption and Transport of Lipids Lipid digestion occurs primarily in the small intestine though a small amount of lipids are broken down in the stomach. Special enzymes called lipases breakdown triglycerides the most abundant lipids in the diet and phospholipids. Lingual lipase secreted by glands in the tongue and gastric lipase secreted by gastric chief cells hydrolyze a small amount of triglycerides into fatty acids and monoglycerides. As chyme enters the duodenum from the…

After stage one, there are both ATP and ADP molecules produced and after stage three there are two ADP molecules produced, a singular hydrogen atom, and a citrate. After the fifth stage, there are two hydrogen atoms produced but they are lost in the sixth due to oxidisation. Between the stages 7-10, two ATP molecules are formed. During glycolysis, the enzymes catalyse numerous reactions and they are controlled by the concentrations of the ATP, ADP, hydrogen+, and citrate. When it comes to…

tremendous amount of weight, indicating an increase in metabolism. In the scientific article “Metabolic Mapping of the Effects of Cocaine during the Initial Phases of Self-Administration in the Nonhuman Primate”, Porrino, Lyons, Miller, Smith, Friedman, Daunias, and Nader trained rhesus monkey to self administer a certain dosage of cocaine and observed the effects of the drug on glucose metabolism. Interestingly, they found that glucose metabolism both increased and decreased according to…

The chemistry of carbohydrates, proteins and minerals plays an important role in running the life process of human body. The chemical reactions and their role in the human body are essential as it fuels the body to carry out the life process, to keep the body healthy and to provide body with energy. Structure of Starch It is formed by units of glucose and is a homopolysaccaride. It is found in the vegetable cells and is composed of two types of homopolysaccaride; Amylopectin and amylose.…

podium. Many athletes try out different diets, supplements, and training techniques to improve their performance. The use of nutritional ergogenic aid in the sports industry is very well known for improving performance. Most ergogenic aids affect the metabolism and the central nervous system to reduce body fat content and stimulate protein synthesis to increase muscle mass or create lean body mass. One of the most used supplements among athletes is creatine, commonly used for increasing muscle…
