PDH
  1. PDH Phosphatase Activates PDH
    1. PDH (Inactive)
      1. Phosphorylated
      2. To Activate PDH Phosphatase
        1. Increased Mg2+ & Ca2+, available from muscular contraction
      3. PDH Kinase Deactivates PDH
        1. To Deactivate PDH kinase
          1. Increased levels of pyruvate, NAD+, CoASH, ADP and Ca2+
            1. CA2+ from muscle contraction
              1. During exercise pyruvate increases due to enhanced glycolysis = PDH activated. ADP increases due to ATP hydrolysis
            2. To activate PDH Kinase
              1. Increased levels of ATP, NADH and Acetyl CoA
                1. When glycolysis and beta-oxidation occur rapidly result in build up of acetyl CoA.
              2. PDH (Inactive)
              3. Dephosphorylated
                1. Forms acetyl CoA from Pyruvate
                  1. Regulates CHO and Lipid oxidation
