Which term refers to the building up of substances in metabolism?

• A. Anabolism
• B. Catabolism
• C. Homeostasis
• D. Metabolism

Answer: (A)

Anabolism is the constructive part of metabolism, where smaller molecules are assembled into larger ones, such as amino acids forming proteins or simple sugars forming glycogen. This process requires energy and underpins growth, repair, and storage in the body. In contrast, catabolism breaks down large molecules to release energy, metabolism is the umbrella term for all chemical processes, and homeostasis refers to maintaining stable internal conditions. So the term for the building up of substances in metabolism is anabolism.
