˙ 一次傳遞過程中會轉移兩個氫(H+ -e-),其中以coenzyme Q為最重要的Cofactor,因為它是氧化還原反應的當量點,電子都會經過coenzyme Q,I跟II都會經過coenzyme Q,III跟IV則不會,因為III跟IV是傳遞出去的
B. 血紅素(Heme)和鐵硫中心(Iron sulfur center):
˙ 用Fe3+-->Fe2+ 去轉移一個電子(用FeS:鐵硫蛋白去轉移)

Oxidoreductases consist of a large class of enzymes catalyzing the transfer of electrons from an electron donor (reductant) to an electron acceptor (oxidant) molecule, generally taking nicotinamide adenine dinucleotide phosphate (NADP) or nicotinamide adenine dinucleotide (NAD) as cofactors. oxidoreductase introduction
