Verified step by step guidance1
Understand the concept of the electron transport chain (ETC): The ETC is a series of protein complexes located in the inner mitochondrial membrane that transfers electrons from electron donors to electron acceptors via redox reactions.
Identify the role of electron carriers: In the ETC, NADH and FADH2 donate electrons, which are passed through a series of complexes.
Recognize the final electron acceptor: In the ETC, the final electron acceptor is the molecule that receives electrons at the end of the chain.
Explain the role of oxygen: Oxygen is the final electron acceptor in the electron transport chain. It combines with electrons and protons to form water.
Summarize the importance of oxygen: Without oxygen as the final electron acceptor, the electron transport chain would halt, preventing ATP production through oxidative phosphorylation.
