Question

which label identifies the part of the atp molecule that changes when energy is released in the cells of all living th diagram of atp molecule with labels a, b, c, d; multiple - choice options: a, b, c, d

Explanation:

ATP (adenosine triphosphate) releases energy when the high - energy phosphate bond between the last two phosphate groups is broken, converting ATP to ADP (adenosine diphosphate) by losing one phosphate group. In the ATP structure, label C is likely the last phosphate group (or the part related to the phosphate group that is removed when energy is released). Label A is probably the adenine part, label B is a phosphate group but not the one typically removed for energy release, and label D is the ribose sugar. So the part that changes (loses a phosphate) when energy is released is related to label C.

Answer:

C
