Metabolism is Defined As

Question

Metabolism is defined as
A) any individual process in the body.
B) all the structures in the body.
C) all of the homeostatic setpoints in the body.
D) all of the chemical reactions in the body
E) the collection of all of the organs in the body and their parts.

Accepted Answer

Metabolism refers to the sum total of all chemical reactions that occur within the body, including anabolic (building up) and catabolic (breaking down) processes. Therefore, option D is the correct choice. Option A is too narrow as it refers to only individual processes, while option B, C, and E are too broad as they encompass structures, setpoints, and organs, respectively, which are not all related to metabolism.
