Question

During glycolysis, when glucose is catabolized to pyruvate, most of the energy of glucose is a. retained in the pyruvate. b. transferred directly to FADH2. c. transferred to ADP, forming ATP. d. stored in the ADP produced.

Answer 1

Answer:

a. retained in the pyruvate

Explanation:

Glycolysis is a cytoplasmic pathway that converts glucose into two pyruvate, releasing a modest amount of energy captured in two substrate-level phosphorylations and one oxidation reaction.

Following are the important enzymes in it :

1. Hexokinase
2. Phosphofructokinase
3. Pyruvate kinase

Aerobic glycolysis yields 2ATP/glucose plus 2NADH/glucose but most of the energy is retained in pyruvate which is then converted into Acetyl-CoA and enters the kreb's cycle.
