Glycolysis
1. Glucose (6C)
  1. Glucose phosphate (6C)
    1. Fructose phosphate (6C)
      1. Fructose biphosphate (6C)
        2x Triose phosphate (3C)
        2x GP (3C)
        2x Pyruvate (3C)
        2ADP
        2ATP
        2ATP
        2rNAD
        2ADP
        2NAD
      2. ATP
      3. ADP
  2. ATP
  3. ADP
2. Yield: 2Pyruvate 2ATP (net) 2rNAD
3. Occurs in the cytoplasm of all cells
4. DOES NOT REQUIRE OXYGEN
5. purpose is to create pyruvate for link reaction
Link Reaction and Krebs Cycle
1. Pyruvate
  1. Acetyl CoA
    1. Acetate (2C)
      1. Citrate (6C)
        5C Compound
        4C Compound
        4C Compound
        4C Compound
        Oxaloacetate (4C)
        rNAD
        rNAD
        ATP
        CO2
        rNAD
        CO2
        rNAD
    2. CoA
  2. CO2
2. Occurs in the matrix of mitochondria
3. Purpose is to create rNAD and rFAD for ETC
Electron Transport Chain
1. 1. 1. 1. 2e-
        1/2 O2 + 2H+
        H2O
        MATRIX
      2. H+
      3. H+
      4. H+
        H+
      5. INTERMEMBRANE SPACE
      6. H+
        ADP + PI
        ATP
    2. H+
    3. H+
    4. H+
    5. H+
    6. H+
  2. rNAD/rFAD
    1. NAD/FAD
  3. 2H
    1. 2e-
    2. H+
      1. H+
        H+
2. Hydrogen atoms are split into protons (H+) and electrons (e-)
  1. Electrons move along the ETC, losing energy
    1. This energy is used to actively transport protons from the matrix to the intermembrane space
      1. Some energy is used to combine ADP + Pi to ATP
        Electrons combine with protons to form water (FINAL ELECTRON ACCEPTOR)
