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-phosp...

What are the two stages of glycolysis - energy investment stage and energy payoff stage (hexose-triose) How many ATP are consumed and produced in glycolysis - 2 are consumed and 4 are produced How many NADH are produced during glycolysis? - 2 Pyruvate pathways in aerobic vs anaerobic environments - Aerobic: Pyruvate is oxidized in the CAC and its low potential electrons then convert NAD+ to NADH, which is oxidized in the ETC to produce ATP Anaerobic: It is converted to lactate in human...

HHP 3114 Unit 1 Exam Study Guide | Complete Solutions (Answered) Without ATP we cannot what? Function What is THE fuel for high intensity? Can we exhaust these? carbohydrates, we can exhaust these What is an endless supply of energy for us? lipids (fat) Describe lipids ATP wise big time contributor to ATP production at lower intensity Triglycerides → glycerol → fatty acid → get it into the muscle fiber → get it to the mitochondria etc etc AKA- this TAKES TIME! So not for high intensiti...

For a 63kg adult female performing a 30 second anaerobic power (Wingate) test and a 90 second anaerobic capacity test (on separate days!), what will be the correct flywheel resistance(s) to use? - correct answer5.4kp (power) & 3.2kp (capacity) True or false: during a 90 second anaerobic capacity test, it is important that the subject does not pedal too fast at the start of the test or they risk fatiguing excessively towards the end of the test. - correct answerFalse The Wingate 30 second s...
