Question

The entire set of chemical reactions that sustain life is called:
A)metabolism.
B)catabolism.
C)anabolism.
D)hydrolysis.
E)plasmolysis.

Accepted Answer

Metabolism includes all of the chemical processes that occur within an organism in order to maintain life. This includes both catabolism (the breakdown of molecules for energy) and anabolism (the synthesis of new molecules for growth and maintenance). Hydrolysis is a specific type of chemical reaction that breaks down molecules with the addition of water, while plasmolysis refers to the shrinking of a cell due to water loss.
