Question

What is the role of oxygen in cellular respiration

Answer 1

The site above can help. It says that... "Without oxygen, cellular respiration could not occur because oxygen serves as the final electron acceptor in the electron transport system. The electron transport system would therefore not be available. Glycolysis can occur without oxygen. Although glycolysis does not require oxygen, it does require NAD+. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis

Answer 2

Answer: Cellular respiration is the process by which the glucose is broken down and energy is produced in the form of adenosine triphosphte in the presence of oxygen.

Explanation: During this process hydrogen and its bonding electrons exchange its partners.

The hydrogen and its bonding electrons move from glucose to the oxygen which forms water and adenosine tri phosphate.

This hydrogen transfer to oxygen makes it so useful in cellular respiration.
