The process by which a cell converts nutrients into energy or materials is called:
a. digestion
b. metabolism
c. nutrition
d. endurance

Metabolism is the correct answer. During metabolism, the nutrients are broken down by the action of enzymes, and are converted into energy, in the form of ATP. This process may be aerobic and anaerobic. Different end products are formed in both, but ATP is produced in both processes.
