Question

during cellular respiration, what is the role ofoxygen?? A. it is reduced during glycolosis as glucose isoxidized B. it provides electrons to the electron transport chain C. it combines with carbon during the citric acid cycle toform CO2 D. it requires the production of heat and light E. it accepts electrons from the electron transportchain during cellular respiration, what is the role ofoxygen?? A. it is reduced during glycolosis as glucose isoxidized B. it provides electrons to the electron transport chain C. it combines with carbon during the citric acid cycle toform CO2 D. it requires the production of heat and light E. it accepts electrons from the electron transportchain

Explanation / Answer

      E. it accepts electronsfrom the electron transport chain           Cellular respiration is the complete oxidation of foodmaterilas.            Thisincludes glycolysis, citric acid cycle and electron transportchain.           The reductants that aregenerated in the glycolysis and citric acid cycle enter theelectron transport chain and pass             theirelectrons through different electron carriers and finally passtheir electrons to oxygen.             Thismeans the final acceptor of electrons is oxygen which means thatthe electrons from electron transport chain             areaccepted by oxygen.             Hopeyou are satisfied with the answer.
