Adenosine triphosphate

Adenosine Triphosphate (ATP) is the body’s main source of chemical energy. It is produced by breaking down nutrients such as glucose, fatty acids and proteins, which are all found in food. At the start of the race, anaerobic pathways are used to provide a quick source of energy. Most of this energy is derived from the catabolism of fats. Since lipids are more reduced than carbohydrates, they are capable of storing more energy per unit weight. Triacylglycerols are the lipids used for energy storage. They are comprised of three fatty acids linked to a glycerol molecule. Triacylglycerols are stored by animals in adipocytes, which collectively make up adipose tissue, and also in the liver. Mobilisation of triacylglycerols is important in the hours…

5.0 Discussion 5.1 Adenosine Triphosphate System In touch football there are three systems used throughout the duration of the game these are the ATP system (Adenosine Triphosphate), the Lactic Acid system (anaerobic glycolysis) and the final system the Aerobic system. ATP doesn’t exist in the muscles and tissues waiting to supply abundant amounts of energy (Hede, Russell and Weatherby), ATP is a chain consisting of three phosphate groups. To produce energy the phosphate chain breaks and one…

Adenosine triphosphate (ATP) is the main energy carrier within cells. ATP is a nucleotide and consists of adenine, a ribose sugar and a triphosphate unit. ATP is “an energy-rich molecule because its triphosphate unit contains two phosphoanhydride bonds” and, a significant amount of energy is released when these bonds are broken1. Oxidative phosphorylation is a metabolic pathway whereby mitochondria in living cells generate ATP from the oxidation of nutrients. This process involves the transfer…

This process creates energy and we all need energy to survive. The three stages of Cellular respiration are Glycolysis, The Kreb’s Cycle and The Electron Transport chain. Glycolysis is the first step to cellular respiration. There are 2 stages that make Glycolysis happen. The first is the “Investment” stage. As you consume food, glucose is consumed and passed through the cytoplasm. In order for the investment stage to begin, you need to use energy to start it. Unlike the other two processes,…

absence of muscle fatigue. This suggests that the neural drive is stimulated by the central mechanism. This may then cause muscle recruitment efficiency (St Clair Gibson and Noakes 2004). Peak power output, however, indicated discrepancies throughout the trial for the current investigation. Adenosine triphosphate measurements was beyond the scope of this study. Nevertheless, previous observations demonstrated power reduction is associated with the rapid depletion of Adenosine triphosphate…

Rigor Mortis The term rigor stems from the Latin term meaning stiffness. Mortis stems from the Latin term meaning death. Upon death, respiration ceases to occur. Without oxygen, metabolism stops, organs shut down. The body’s main source of energy is the cell production of ATP. Wikipedia’s definition:” Adenosine triphosphate (ATP) is a nucleoside triphosphate used in cells as a coenzyme often called the "molecular unit of currency" of intracellular energy transfer. ATP transports chemical…

Adenosine Triphosphate (ATP) is a nucleic acid present in organisms with the primary function of providing energy. It is comprised of three phosphate groups with one adenosine attached and releases energy by being hydrolysed into Adenosine Diphosphate (ADP), therefore one bond is broken and a phosphate molecule is lost. ATP can only be reproduced through phosphorylation which results in the addition of one phosphate to Adenosine Diphosphate. ATP must be regenerated in order to allow an organism…

contraction, which is known as the crossbridge. At first, this crossbridge is extended with adenosine diphosphate (ADP) and inorganic phosphate (Pi) attached to the myosin. When the crossbridge is formed, the myosin head bends, thus generating force and sliding the actin filament past the myosin. This is known as the power stroke in which myosin releases ADP and Pi. After they have been released, adenosine triphosphate (ATP) molecule attaches to the myosin. The myosin discharges the actin…

The citric acid cycle generates energy from the oxidation of various fuel molecules to acetyl coenzyme A (acetyl CoA). Acetyl CoA undergoes several redox, hydration and decarboxylation reactions to produce carbon dioxide (CO2), reduced nicotinamide adenine dinucleotide (NADH), reduced flavin adenine dinucleotide (FADH2), adenosine triphosphate (ATP) and hydrogen ions. The citric acid cycle links glycolysis which produces pyruvate from glucose and oxidative phosphorylation which generates ATP…
