Document Summary
O2 is not involved in converting anything to. Oxygen gets converted to water in etc but it is not a good reducing agent so it will oxidize nadh to nad+ The riboflavin group is important to allow enzyme processes to go on. Dinucleotide sugar, base, and some phosphates. Cofactor that is usually permanently bound to an enzyme. Flavin adenine dinucleotide (fadh2: iron sulfur centers, each centre can accept one electron (fe3+ fe2+, examples, ubiquinone=coenzyme q=q, lipid in inner mitochondrial membrane, accepts two electrons, q = oxidized form, qh2 = reduced form, hydrophobic molecule. Does not like to be floating around in aqueous solution, but found in the membrane. Each copper accepts one electron (cu2+ cu+) Electron transport protein complexes: the flow of electrons from nadh, final stage converting oxygen into water, 3 complexes 1, 3 and 4 are involved, complex 1 accepts electrons from nadh and they go on to coenzyme q.
