| The major role of red cells is to transfer oxygen from the lungs to the tissues. |
| Some bacteria are able to switch from enzymes using oxygen as a terminal electron acceptor to enzymes using alternative electron acceptors. |
| Xanthine oxidase uses molecular oxygen as an electron acceptor, resulting in the formation of superoxide radicals. |
| The reason we need to breathe is to provide the oxygen needed to carry out cellular respiration in our cells. |
| This enzyme uses inorganic oxygen as an electron acceptor and H 2 O 2 is formed that has to be detoxified by a catalase. |
| Nadp is much preferred to oxygen as an electron acceptor in intact chloroplasts. |
