| | | | | |

|Process |Where occur? |Main Function/ Components |Inputs |Outputs |

| |Cytoplasm |Oxidation of glucose to 2 pyruvate |1 glucose |2 pyruvate |

| | | |2 ATP |4 ATP (substrate level) |

| | | |2 NAD+ |2 NADH |

|Glycolysis | | | | |

| | | |(4 ADP) | |

| |Matrix of mitochondria |Oxidation of pyruvate to acetyl-CoA |2 pyruvate |2 acetyl-CoA |

| | | |2 NAD+ |2 NADH |

|Pyruvate to Acetyl CoA | | | |2 CO2 |

| |Matrix of mitochondria |Oxidation of acetyl-CoA into NADH & FADH2 |2 acetyl-CoA |4 CO2 |

| | | |6 NAD+ |6 NADH |

| | | |2 FAD |2 FADH2 |

|Krebs Cycle | | |2 ADP |2 ATP |

| |Inner membrane |NADH & FADH2 transfer electrons to ETC; go through redox reactions with O2 as final electron |10 NADH |10 NAD+ |

| | |acceptor; this generates proton motive force; proton motive force used to drive synthesis of ATP |2 FADH2 |2 FAD |

|Electron transport chain & | |by ATP synthase |O2 |H2O |

|oxidative phosphorylation | | | |32-34 ATP |

| | | | | |
