The breakdown of proteins only

The process of creating energy through sleep

The sum of all chemical reactions either using or creating energy

Metabolism refers to all chemical processes in the body that involve energy, including the breakdown of proteins, the creation of energy through sleep, and the digestion of food. Option A is incorrect because it only refers to the breakdown of proteins, which is only one aspect of metabolism. Option B is incorrect because while sleep does play a role in metabolism, it is not the only process involved. Option D is incorrect because metabolism involves much more than just the digestion of food. Therefore, option C is the most accurate answer as it encompasses all aspects of metabolism.
