Document Summary
Two carbons are oxidized to co2 to reduce the electron carriers nad+ and fad to nadh and fadh2. The electrons are delivered to o2 through many intermediates. The energy released by these redox reactions are used to pump protons. Oxidative phosphorylation: the process of transferring electrons from one carrier to another to form. Cofactor: a non-protein chemical group that enables an enzyme to catalyze a reaction. Give proteins functional capabilities not provided by amino acids. Coenzyme: a cofactor that is mostly an organic (i. e. , carbon-based) molecule. Prosthetic group: a cofactor that remains tightly bound to the enzyme. Coenzymes are chemically changes as the reaction is catalyzed, so they can be considered substrates. Most are embedded in the four large integral membrane protein complexes of the electron transport chain. Electron carriers differ in their af nity for electrons. Electrons pass from a carrier with low af nity to a carrier with higher af nity.
