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

i. is broken down to fuel chemical reactions.

ii. is created by chemical reactions.

Explanation:

Metabolism is the set of chemical reactions that produce the energy necessary to carry out the vital functions of living beings. Metabolism can be divided into anabolism and catabolism.

Glucose (C6H12O6) is the energy fuel for cells. When it is broken it releases energy from its chemical bonds and waste. It is this energy that allows the cell to perform its metabolic functions.

Before understanding the processes of obtaining energy, you must know how the energy is stored in the cells until use. This occurs thanks to ATP (Adenosine Triphosphate), the molecule responsible for the capture and storage of energy. It stores in its phosphate bonds the energy released in the breakdown of glucose. During metabolism, this ATP is broken down to fuel chemical reactions and is also created by chemical reactions.
