5.1 Metabolism
  • Metablolism refers to all chemical reactions that occur in a living organism.
  • There are two types of metabolism in a cell which are catabolism and anabolism.
Catabolism Anabolism
  • The process of breaking down complex substances into simple substances.
  • Releases energy.
  • Example: The breakdown of glucose during cellular respiration to generate energy.
  • The process of synthesising complex molecules from simple molecules.
  • Uses or absorbs energy.
  • Example: The formation of glucose during photosynthesis.
