Detailed explanation-1: -ATP hydrolysis provides the energy needed for many essential processes in organisms and cells. These include intracellular signaling, DNA and RNA synthesis, Purinergic signaling, synaptic signaling, active transport, and muscle contraction.
Detailed explanation-2: -ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.
Detailed explanation-3: -Energy from ATP is used to fuel all manner of chemical reactions, including those required for copying DNA and building proteins. In these reactions, enzymes oversee the transfer of energy from ATP hydrolysis to the formation of another chemical bond.
