BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level.

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 the most common energy source in most cellular metabolism. However, some other cellular metabolism were not driven by ATP. Such an example of the other energy currency used in cellular metabolism is guanosine triphosphate (GTP), uridine triphosphate (UTP), and cytidine triphosphate (CTD).

Detailed explanation-4: -Adenosine triphosphate (ATP) is an organic compound that provides energy to drive many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis.

Detailed explanation-5: -There are other energy storage molecules in the cell, like NAD and FAD, but the ATP system is the most common, and the most important.
