Answer:
The correct answer is : 1. Catabolic reactions, 2. Anabolic reactions
Step-by-step explanation:
Metabolism is a set of life-sustaining, enzyme-regulated cellular chemical reactions occurring in organisms. The two types of metabolic reactions are: Catabolic reactions and Anabolic reactions.
The catabolic reactions involve breaking down the complex molecules to simpler molecules. Whereas, anabolic reactions involve synthesizing the complex molecules from the simpler ones.
The catabolic reactions release energy. Whereas, the anabolic reactions require energy.
