Which statement is an example of the chemical potential energy in adenosine triphosphate (atp) being turned into work?
(a) atp is bound by an enzyme but is not hydrolyzed.
(b) atp is spontaneously hydrolyzed to adp.
(c) after splitting atp, a protein changes shape to pump ions across a membrane.
(d) a phosphate group is transferred from atp to glucose during glycolysis.
(e) atp synthase transfers a phosphate to adp.

The correct answer is option (C) "After splitting ATP, a protein changes shape to pump ions across a membrane".

Explanation:

Adenosine triphosphate (ATP) is an organic chemical molecule considered the "molecular unit of currency" of intracellular energy transfer, for the high level of energy that is released when ATP is breakdown into adenosine diphosphate (ADP). ATP provides energy to drive many processes in living cells. One example of how the chemical potential energy of this molecule is turned into work is that after splitting ATP, a protein changes shape to pump ions across a membrane. The energy of the splitting of ATP into ADP will provide energy for the protein being able to change shape, resulting in pumping ions across a membrane.
