1. Metabolism and Reaction Types

Key Concepts & Definitions

  • Metabolism: The sum of all chemical reactions that occur in living organisms, converting reactants into products.
  • Anabolic reactions: Form macromolecules from monomers by condensation reactions and require energy, making them endergonic.
  • Catabolic reactions: Hydrolyse macromolecules into monomers and release energy, making them exergonic.

Essential Points

  • Examples of anabolic reactions include protein synthesis, glycogen formation, and photosynthesis.

  • Examples of catabolic reactions include digestion and oxidation of substrates during respiration.
