Metabolism is best described as ____
A
synthesis of macromolecules
B
breakdown of macromolecules
C
control of enzyme activity
D
control of enzyme activity in te synthesis and breakdown of macromolecules
Explanation: 

Detailed explanation-1: -What Is Metabolism? Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.

Detailed explanation-2: -Regulation of metabolic pathways includes regulation of an enzyme in a pathway by increasing or decreasing its response to signals. Control involves monitoring the effects that these changes in an enzyme’s activity have on the overall rate of the pathway.

Detailed explanation-3: -Metabolism can be split into a series of chemical reactions that comprise both the synthesis and degradation of complex macromolecules known as anabolism or catabolism, respectively.

Detailed explanation-4: -Catabolism is the set of metabolic processes that break down large molecules.
