What molecule releases energy to power the transport work across cell membranes?

Question

Quizplus · Accepted Answer

ATP (adenosine triphosphate) is the molecule that releases energy to power transport work across cell membranes. ATP is produced during cellular respiration or photosynthesis and contains high-energy phosphate bonds, which can be broken to release energy for cellular work. Therefore, ATP is often referred to as the "energy currency" of the cell. ADP (adenosine diphosphate) is a lower-energy molecule that is formed when ATP is used for cellular work and loses one of its phosphate groups. NADP and NADPH are involved in cellular redox reactions but are not directly linked to transport work across cell membranes.
