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.

7. Where does glycolysis occur?

  • Ribosome
  • Mitochondrial Matrix
  • Chloroplast
  • Inner-mitochondrial membrane
