HPHY 371 Exercise Physiology exam 2024
Which energy system supports the greatest maximum rate of ATP synthesis? - ATP-PC Which muscle cells will experience glycolysis ending in lactate as a result of contraction? - Type 1, Type 11a, Type 11x = all muscle fibers capable of all energy systems During heavy exercise, glycolysis is anaerobic because there is low oxygen available in the cell. (t/f) - False- there is always enough oxygen, it simply cannot be utilized during heavy exercise What inhibits hexokinase? - glucose-6-phosphate What stimulates and inhibits PFK? - Stimulates: ADP, P, AMc Inhibits: ATP, CP, Citrate What stimulates and inhibits Pyruvatekinase? - Stimulates: ADP Inhibits: ATP, Citrate What inhibits lactate dehydrogenase? - ATP What are anaerobic energy systems? - ATP-PC Glycolytic When contracting during exercise, which muscle fibers will result in glycolysis ending in lactate? - Type 1 = slow oxidative Type 2a = slow oxidative glycolytic Type 2x = fast glycolytic -- all of them What is the fate of NADH in glycolysis? - 1. Turns to lactate 2. Goes to ETC NADH acts like a shuttle for electrons via * Malate-aspertate shuttle or * Glycerol Phosphate shuttle
