When atp is broken down in cells, and are the products. a. adenosine diphosphate; a phosphate group b. adenosine monophosphate; three phosphate groups c. adenosine triphosphate; a phosphate group d. adenosine diphosphate; three phosphate groups

The correct option is A. When ATP is broken down in cells, adenosine diphosphate and a phosphate group  are the products.

Explanation:

Adenosine triphosphate (ATP) is made when an Adenosine diphosphate molecule gains a phosphate atom. This process is termed as phosphorylation. Energy is stored in this bond between the ADP and the phosphate molecule.

ATP is the main molecule which every cell in the body utilizes for energy. The breakdown of ATP drives the energy needed for the cells to action.

When an ATP molecule is broken down, adenosine diphosphate (ADP) and a phosphate group are released along with energy.
