Final answer:
Catabolic processes in biology are linked to anabolic reactions in metabolism. They involve the breakdown of larger molecules and the synthesis of smaller ones using the released energy.
Step-by-step explanation:
Catabolic Processes Coupled to Anabolic Reactions in Metabolism
Catabolic processes in biology are coupled to anabolic reactions in a metabolic pathway. Catabolic reactions break down larger molecules into smaller ones, releasing energy. Anabolic reactions use this energy to synthesize larger molecules. Both processes are essential for maintaining life.
Examples:
- Catabolic reaction: The breakdown of carbohydrates, lipids, and proteins from ingested food into smaller constituent parts.
- Anabolic reaction: The synthesis of proteins from amino acids, using the energy released by catabolic reactions.
