When glucose is catabolized to pyruvate in glycolysis, most of its chemical energy is:
a. transferred to ADP, forming ATP
b. transferred directly to ATP
c. retained in pyruvate
d. stored in the NADH produced

Question

When glucose is catabolized to pyruvate in glycolysis, most of its chemical energy is:
a. transferred to ADP, forming ATP	
b. transferred directly to ATP	
c. retained in pyruvate
d. stored in the NADH produced

anonymous · Answer

c. retained in pyruvate. A little energy goes into forming NADH, but the amount of energy still capable of being won from the pyruvate is a lot larger, which can be seen by the fact that several more NADH and NADPH are made in the citric acid cycle.
