- Respiration
- 1. Glycolysis (cytoplasm)
- Phosphorylated glucose (2 ATP used)
- 2x triose phosphate
- 2x Pyruvate (4 ATP made and 2 NAD used)
- 2x triose phosphate
- Phosphorylated glucose (2 ATP used)
- 2. Link Reaction (matrix)
- Pyruvate - hydrogen = acetate
- NAD becomes reduced NAD
- acetyl CoA (1C formed)
- NAD becomes reduced NAD
- Pyruvate - hydrogen = acetate
- 3. Krebs cycle (matrix)
- Acetyl CoA binds with 4C to form 6C.
- 4H lost - 3 NAD reduced and 1 FAD reduced.
- 2C lost
- 1 ATP formed
- 4C regenerate
- Acetyl CoA binds with 4C to form 6C.
- 4H lost - 3 NAD reduced and 1 FAD reduced.
- 2C lost
- 1 ATP formed
- 4C regenerate
- Acetyl CoA binds with 4C to form 6C.
- Acetyl CoA binds with 4C to form 6C.
- 4. Electron Transport Chain (cristae)
- Reduced NAD and FAD becomes oxidised, releasing H atoms which are split into H+ and e-
- Electrons move along ETC in oxidation-reduction reactions.
- Energy lost is used to make ATP.
- H+ protons accumulate between mitochondria membranes then diffuse into matrix.
- Water is formed. Oxygen is final acceptor of electrons.
