Which description properly describes a step involved in cellular respiration? glucose is broken apart, then the energy gained is transferred to the energy molecule. carbon dioxide is combined with oxygen to make glucose. water is divided into carbon dioxide and glucose. oxygen is combined with the energy molecule to energize it.

Option A is correct.  In Cellular respiration Glucose is broken down to  gain energy and transfer to the energy rich molecule (ATP).

Cellular Respiration:

It is the process by which organisms form energy rich molecule called ATP.

This includes,

Hence, we can say that Option B, C, and D is incorrect.

Therefore we can say that the, in cellular respiration Glucose is broken down to gain energy and transfer to the energy rich molecule (ATP).
