In order to function properly, cells must perform many reactions. metabolism is the sum of all the chemical reactions in an organism. during metabolism, atp i. is broken down to fuel chemical reactions. ii. is created by chemical reactions. iii. is shuttled from one cell to another.

The correct answer is option i.

Explanation:

ATP or adenosine triphosphate refers to an essential chemical in the metabolism of a human being, which is known as the chemical currency as the cells utilize it as a direct source of energy. The cells after producing ATP can utilize it to meet the requirements of energy.  

The cells require energy to produce big molecules like hormones. The muscle cells utilize ATP to generate motion. As a cell produces a molecule of the hormone, it dissociates the molecules of ATP and utilizes the energy to generate new bonds between the smaller molecules in order to develop a bigger one.
