D
Cytochrome c
검증된 단계별 안내1
Understand the electron transport chain: It is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane.
Identify the role of electron carriers: In cellular respiration, electron carriers like NADH and FADH2 donate electrons to the electron transport chain, which are then passed through a series of complexes.
Recognize the function of Complex III: Complex III, also known as cytochrome bc1 complex, receives electrons from ubiquinone (Coenzyme Q) and transfers them to cytochrome c.
Clarify the role of ubiquinone (Coenzyme Q): Ubiquinone is a lipid-soluble electron carrier that transfers electrons from Complex I and II to Complex III.
Understand the role of cytochrome c: Cytochrome c is a small protein that transfers electrons from Complex III to Complex IV in the electron transport chain.
