Question

which of the following is an example of catabolism?
multiple choice
26
glycolysis
protein synthesis
maintaining cell structure
synthesis of atp
production of hormones

Explanation:

Catabolism is the set of metabolic processes that break down large molecules into smaller units, often releasing energy. Glycolysis is the breakdown of glucose (a large molecule) into pyruvate (smaller units) with the release of some energy (in the form of ATP and NADH). Protein synthesis is an anabolic process (building up proteins from amino acids). Maintaining cell structure is more of a general cellular function that isn't specifically a catabolic reaction. Synthesis of ATP can be part of both catabolic (e.g., during glycolysis, Krebs cycle) and anabolic (e.g., in photosynthesis) pathways but glycolysis itself is a clear - cut catabolic process. Production of hormones (which are often proteins, steroids etc.) is anabolic as it involves building these molecules.

Answer:

Glycolysis
