Answer:
C) accepting electrons at the end of the electron transport chain
Explanation:
Cellular respiration is a series of reactions which is associated with the oxidation of glucose. The respiration reactions are divided into 4 phases: Glycolysis, Pyruvate decarboxylation, Krebs cycle and electron transport chain.
The cellular respiration usually takes place in the presence of oxygen which is not utilized until the last stage of the electron transport chain. In the electron transport chain, the oxygen acts as an electron acceptor as it accepts the electron and is converted to metabolic water.
Thus, the selected option is the correct answer.
