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.

Memory Hook

Build or break

2. Energy in Living Organisms

Key Concepts & Definitions

  • Kilocalorie : The amount of heat energy needed to increase the temperature of 1 g of water by 1°C.
