Which of the following describes how ATP provides energy to cellular processes?

Energy in cells is supplied by ATP through phosphorylation: ATP donates a phosphate group to target molecules. This phosphate transfer changes the substrate’s shape and chemical reactivity, enabling it to participate in or accelerate cellular processes. The energy released when the terminal phosphate is removed (ATP becoming ADP and Pi) powers these tasks, such as enzyme activation, membrane transport, and motor activities. This mechanism explains why ATP is described as the energy currency of the cell. Other options don’t describe how ATP provides energy: ATP isn’t creating water, converting energy into light, or merely consuming energy—the essential point is phosphate transfer to drive work.
