Verified step by step guidance

Understand the concept of a redox reaction: In cellular respiration, redox reactions involve the transfer of electrons from one molecule to another. The molecule that donates electrons is oxidized, and the molecule that accepts electrons is reduced.

Identify the role of oxygen in cellular respiration: Oxygen acts as the final electron acceptor in the electron transport chain, a crucial part of cellular respiration. This process occurs in the mitochondria of cells.

Recognize the importance of the electron transport chain: During cellular respiration, electrons are transferred through a series of proteins embedded in the inner mitochondrial membrane, known as the electron transport chain.

Explain the reduction of oxygen: As electrons move through the electron transport chain, they eventually reach oxygen, which combines with protons (H⁺) to form water (H₂O). This is the final step in the electron transport chain.

Summarize the role of oxygen: Oxygen's role as the final electron acceptor is essential for the production of ATP, the energy currency of the cell, during cellular respiration.
