  3. In all cases the substrate loses two electrons, or is oxidized, to the product.

  4. All of these are common forms of cellular energy.

  5. The chemical and redox energy from glycolysis, the TCA cycle, and fatty acid oxidation all are used to generate a proton gradient across a membrane. This gradient is, in turn, converted to a common currency of chemical energy, ATP.
