I took the same test the answer is metabolism

The right answer is metabolism.

Metabolism defines the set of coupled reactions occurring in the cells of the body. It consists of two opposing mechanisms:

* Catabolism: it allows the extraction of energy from nutrients, by degradation of energy molecules (carbohydrates, lipids ...);

* Anabolism: it allows to synthesize the constituents necessary for the structure and the proper functioning of the cells.

Basal metabolism is also contrasted with metabolism in activity.
