When ATP Breaks Down into ADP and a Phosphate Group

Question

When ATP breaks down into ADP and a phosphate group,
A)energy is absorbed by ADP and transferred to enzymes.
B)energy is released and can power cellular activities.
C)ADP becomes the active site in an enzyme.
D)the energy in the broken bond is transferred to the phosphate group.

Accepted Answer

When ATP (adenosine triphosphate) breaks down into ADP (adenosine diphosphate) and a phosphate group, energy is released, which can be used to power cellular activities. This release of energy is due to the breaking of the high-energy phosphate bond in ATP. The energy is not absorbed by ADP but released, and it can transfer to other molecules to fuel metabolic reactions or cellular work.
