Document Summary
Coenzyme = organic cofactor, often a rxn substrate. Coenzyme could be a substrate- generally would be changed in the course of a. Brings a different chemistry to the protein enzyme allowing for it to do its job. Could be a metal ion or a coenzyme but tightly bound and never disassociated. Overview of citric acid cycle: reaction (enzymes not changed) coenzymes are. Nadh and fadh2 from the citric acid cycle and an nadh from pyruvate dehydrogenation: add electrons from matrix side. Electrons transferred in the inner membrane space and ultimately end up on oxygen. Point of etc: proton pump: get a larger concentration of protons in the intermembrane space than in matrix which can be used as a source of potential energy (theres a concentration difference/electrical difference) across the membrane. Remember that they are protein bound but non proteins. Think of them in terms of affinity of electrons.
