Krebs cycle (AQA)

View mindmap
  • The Krebs Cycle
    • Yield
      • Reduced coenzymes
        • Eg NAD and FAD
      • 1 ATP molecule
      • 3 CO2 molecules
    • Significance
      • Breaks down macromolecules into smaller ones
        • Pyruvate broken down to CO2
      • Produces H atoms which are carried by NAD to the ETC
        • For oxidative phosphorylation
        • Leads to ATP production
        • Provides metabolic energy to the cell
      • Regenerates the 4-Carbon molecule which combines with acetyl CoA
        • Otherwise it would accumumulate
      • Source of intermediate compounds used for other processes
