Detailed explanation-1: -ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis. These processes, as well as others, create a high demand for ATP.

Detailed explanation-2: -ATP synthesized in mitochondria is the primary energy source for important biological functions, such as muscle contraction, nerve impulse transmission, and protein synthesis.

Detailed explanation-3: -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-4: -Phosphagen system (ATP-CP) The phosphagen system provides ATP primarily for short-term, high-intensity activities (e.g., resistance training and sprinting) and is active at the start of all exercise regardless of intensity.

Detailed explanation-5: -Eukaryotic cells use three major processes to transform the energy held in the chemical bonds of food molecules into more readily usable forms-often energy-rich carrier molecules. Adenosine 5’-triphosphate, or ATP, is the most abundant energy carrier molecule in cells.
