Which best describes adenosine triphosphate (ATP)? A waste product molecule that is produced by cells but cannot be used by them.
A high energy molecule that is used by every cell in the body as an energy carrier.
A process that is used to create energy when oxygen is available to the body.
A process that is used to create energy when oxygen is not available to the body.

a high-energy molecule that is used by every cell in the body as an energy carrier.

A high energy molecule that is used by every cell in the body as an energy carrier.

Explanation:

Adenosine triphosphate, also known as the "energy currency" of the cell is an organic molecule that readily supplies energy to the cells to carry out metabolic and catabolic functions. This molecule consists of a nitrogenous base known as adenine, ribose sugar, and three phosphate molecules. The hydrolysis of ATP provides energy for muscle contraction, nerve impulses, signaling for hereditary materials like DNA and RNA, as well as phosphorylation.
