Question

Define (i) Catabolism (ii) Anabolism..​

Answer 1

Answer:

Anabolism and catabolism are the two broad classes of biochemical reactions that make up metabolism. Anabolism is the synthesis of complex molecules from simpler ones. These chemical reactions require energy. Catabolism is the breakdown of complex molecules into simpler ones.

Answer 2

Answer:

Explanation:

(i) Catabolism is the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions. Catabolism breaks down large molecules into smaller units.

(ii) Anabolism is the set of metabolic pathways that construct molecules from smaller units. These reactions require energy, known also as an endergonic process. Anabolism is the building-up aspect of metabolism, whereas catabolism is the breaking-down aspect. Anabolism is usually synonymous with biosynthesis.
