<h3><u>Answer;</u></h3>
2.It serves as the final acceptor for electrons from the electron transport chain.
<h3><u>Explanation;</u></h3>
- Cellular respiration is the process by which glucose or other organic compounds such as fructose are broken down to generate energy in the form of ATP, that is required to drive cellular or body processes.
- Cellular respiration takes place in the presence of oxygen and occurs in three stages, namely; glycolysis, kreb's cycle and electron transport chain. The end products of cellular respiration is energy in the form of ATP, and water and carbon dioxide as a byproduct.
- The oxygen consumed during cellular respiration is directly involved in accepting electrons at the end of the electron transport chain
The amino acids would change resulting in totally different proteins which is also called a frameshift mutation.
