At the end of the electron transport chain the electrons are taken up by oxygen to generate __________.View Available Hint(s)for Part AheatglucoseATPwater

Breakdown the Problem

1. Identify the role of oxygen in the electron transport chain.
2. Determine what products are formed when oxygen accepts electrons.

Relevant Concepts

• In cellular respiration, particularly during oxidative phosphorylation, electrons are transferred through a series of proteins.
• Oxygen serves as the final electron acceptor in the electron transport chain (ETC).

Analysis and Detail

1. When electrons from the ETC reach oxygen, they combine with protons (H⁺ ions) to form water (H₂O).
2. This reaction can be summarized as follows: $4e^- + 4H^+ + O_2 \rightarrow 2H_2O$

Verify and Summarize

• The immediate product of this reaction is water, which is critical in cellular respiration.
• ATP is generated during the process, but it is not the direct product of oxygen accepting electrons.

Final Answer

At the end of the electron transport chain, the electrons are taken up by oxygen to generate water.
