6. Why does respiration not occur if oxygen is absent?
It is needed for photolysis to produce hydrogen ions and act as the final electron acceptor.
Oxygen cannot act as the final electron acceptor, reduced NAD and FAD cannot unload their hydrogen ions, Krebs, link and Oxidative Phosphorylation cease.
It is needed to carry away CO2 molecules and to produce ATP.
Oxygen cannot hydrolyse the NADH for respiration to continue and the Krebs cycle stops.
