Cofactors can be either inorganic (e.g., metal ions and iron-sulfur clusters) or organic compounds (e.g., flavin and heme). Organic cofactors can be either prosthetic groups, which are tightly bound to an enzyme, or coenzymes, ...

They produce a maximum of 38 ATP + 2 wastes products (H2O + CO2) 2. If O2 is not available then glucose will be metabolized to lactic acid. This reaction produces a ...
