Multiple Choice

In the context of redox reactions, does the electron transport chain require oxygen to function?

Yes, but only in anaerobic conditions.

No, the electron transport chain can function without any electron acceptor.

Yes, oxygen acts as the final electron acceptor.

No, oxygen is not involved in the electron transport chain.

Verified step by step guidance

Understand the role of the electron transport chain (ETC) in cellular respiration: 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.

Recognize the importance of oxygen in the ETC: Oxygen is the final electron acceptor in the chain. It combines with electrons and protons to form water, a crucial step for the continuation of the chain.

Consider the consequences of oxygen absence: Without oxygen, the ETC cannot function properly because there is no final electron acceptor to complete the electron transfer process.

Analyze the options given: The correct statement is that oxygen acts as the final electron acceptor, which is essential for the ETC to function under aerobic conditions.

Conclude that the ETC requires oxygen to function effectively, as it is integral to the process of oxidative phosphorylation, which produces ATP, the energy currency of the cell.
