Bioenergetics
The conversion of Glycogen to Glucose involves this type of heat transfer mechanism
What is exothermic
This is the most critical factor for gas exchange across the respiratory membrane
What is the pressure gradient
The beta-oxidation of palmitic acid (a 16-carbon chain FFA) will result in the completion of this many Krebs Cycles.
What is 8 Krebs Cycles
During prolonged bouts of acute exercise, this metabolic hormone appears first for the regulation of blood glucose levels
What is Glucagon
A barbell back squat is an example of this type of musculoskeletal contraction
What is an isotonic contraction
At the end of testing, Lindsay produced measurements of 37mL of CO2 produced per minute and 45mL of O2 consumed per minute. Based on these outcomes, we can assume she primarily relied upon this fuel source during exercise performance
What is Fat (RER = 0.82)
Dante is a division 1 wrestler who weighs 77.6 kg and has a VO2max of 3.5 L/min. Convert this absolute VO2max to a relative VO2max measurement (round to nearest hundredth place)
What is 45.10 ml/kg/min
This metabolic pathway involves the gluconeogenic reconversion of lactate back to glucose to support musculoskeletal energy needs
What is the Cori Cycle
These sense a reduction in plasma volume, promoting the conservation of renal water via antidiuretic hormone secretion
What are baroreceptors
The actomyosin complex is dependent on the calcium-sensitive conformational change of this protein, which reveals the myosin interaction site on actin
What is Troponin
With greater aerobic fitness, what direction will your crossover point shift and what metabolic adaption(s) does this indicate?
What is (1) to the right and (2) a greater reliance on fat, resulting in glycolytic sparing, at higher exercise intensities
This hypothesis states that exercise training results in direct, functional changes to the inherent cardiac pacemaker
What is the Intrinsic Rate Hypothesis
This metabolite allosterically regulates phosphofructokinase activity by overriding its inhibitors (e.g., ATP and citrate)
What is Fructose-2,6-Bisphosphate
During prolonged exercise, cortisol is secreted from the adrenal cortex for the maintenance of blood glucose levels through the utilization of this metabolic pathway
What is gluconeogenesis
This gene regulates training-induced adaptations at the neuromuscular junction
What is PGC1-a (Peroxisome proliferator-activated receptor gamma coactivator 1-alpha)
