Vedclass · Answer

(B) In the electron transport system $(ETS)$ of cellular respiration,oxygen $(O_2)$ acts as the final electron acceptor.It accepts electrons $(e^-)$ from the last cytochrome in the chain and combines with protons $(H^+)$ from the mitochondrial matrix to form water $(H_2O)$.This process is essential for maintaining the flow of electrons through the transport chain,which allows for the synthesis of $ATP$ via oxidative phosphorylation.
