Explain how catabolism differs from anabolism
What will be an ideal response?
Catabolism and anabolism are two phases of metabolism. Catabolic reactions are those in which a substance is broken down into smaller parts. As a whole, the process releases energy that the cell can harness to drive processes such as ATP production. Anabolic reactions are those in which smaller molecules are combined to make a larger molecule. Anabolic reactions require energy, and anabolism is driven by the energy liberated from catabolism.
