As part of the research experiment, a person undergoes 2 fine needle muscle biopsies to obtain small amounts of tissue for biochem'l analysis. The 1st is taken at the beginning of the experiment while the subject is at rest. The 2nd is taken at the end of 30 mins of aerobic exercise. The activity of the muscle pyruvate dehydrogenase is found to be much higher in the 2nd measurement. Which of the ff biochemical changes would be most likely to produce this effect?
A. decreased ADP
B. decreased intracellular calcium
C. increased acetyl coA
D. increased NADH/NAD+
E. increased pyruvate concentration
