Danny Yoder · Answer 1

(c) energy can be extracted in usable amounts.

Explanation:

Gradual oxidation of glucose ensures that ATP is slowly synthesized almost in as the same quantity as needed for cell's metabolism at a time. Rapid glucose oxidation will result in a large portion of the energy being released as heat, since cells can only store small amounts of ATP at a particular time.

Hence, gradual glucose oxidation by cells ensures that a significant amount of energy extracted during phosphorylation is usable by the cell instead of being lost to heat.

The correct option is c.
