Answer:
accepting electrons at the end of the electron transport chain.
Explanation:
In oxidative phosphorylation, one of the major steps of cellular respiration, oxygen consumption is significant.
Cellular respiration may be defined as a complete set of processes that involves the breakdown of food molecules in the cell with the termination of energy for metabolism.
There are three stages of cellular respiration which are significantly known. They are pyruvate oxidation, the Kreb cycle, and oxidative phosphorylation.
Only oxidative phosphorylation requires oxygen in order to complete, while the rest of the two processes do not require direct oxygen but yes they can not be successfully terminated without oxidative phosphorylation.
Therefore, in oxidative phosphorylation, one of the major steps of cellular respiration, oxygen consumption is significant.
