Straighterline Nutrition FINAL Questions and Answers Already Passed physical fitness ✔✔the ability to perform moderate to vigorous activity without undue fatigue ATP (adenosine triphosphate) �... �✔the main energy currency for cells. Used to promote ion pumping, enzyme activity, and muscular contraction. The immediate source of energy for body functions. ADP (adenosine diphosphate) ✔✔A breakdown product of ATP. Synthesized into ATP using energy from foodstuffs and a phosphate group. phosphocreatine (PCr) ✔✔A high-energy compound that can be used to re-form ATP. It is used primarily during bursts of activity, such as lifting and jumping. creatine ✔✔An organic (i.e. carbon containing) molecule in muscle cells that serves as a part of a high-energy compound (termed creatingphosphate or phosphocreatine) cable of synthesizing ATP from ADP. The primary goal in the use of any fuel (carb, fat, protein) ✔✔to make ATP. First line of defense for resupplying ATP in muscles ✔✔PCr (phosphocreating) The main advantage of phosphocreatine ✔✔It can be activated instantly and can replenish ATP at rates fast enough to meet the energy demands of the fastest and most powerful actions. Disadvantage of phosphocreatine ✔✔Not much of it is made and stored in the muscles Ues of glucose to make ATP can be either __ or __ ✔✔anaerobic or aerobic Anaerobic glucose breakdown ✔✔yields energy fast. It provides most of the energy needed for events that require a quick burst of energy (sprints) Disadvantage of the anaerobic breakdown of glucose ✔✔(1) cannot be sustained for long periods of time and (2) the rapid accumulation of lactic acid greatly increases the acidity of the muscle. pyruvic acid ✔✔a three-carbon compound formed during glucose metabolism, also called pyruvate lactic acid ✔✔A three-carbon acid formed during anaerobic cell metabolism; a partial breakdown product of glucose; also called lactate. Aerobic glucose breakdown is a ___ energy source ✔✔sustained aerobic breakdown of glucose yields approximately __ percent of the ATP made from complete glucose metabolism ✔✔95%. Products of aerobic glucose breakdown ✔✔carbon dioxide and water as opposed to the lactic acid of anaerobic glucose breakdown bonking ✔✔diminished mental ability as the result of blood glucose declining during exercise Fall in blood glucose during exercise is related to the depletion of ____ glycogen ✔✔liver (not muscle0 ____ glycogen is used to maintain blood glucose ✔✔liver what is the main fuel for prolonged low-intensity activity ✔✔fat [Show More]
