Questions and Answers

What is the primary function of oxygen in the metabolic processes of cells?

  • To support cellular energy production (correct)
  • To inhibit the production of haemoglobin
  • To synthesize CO2 as a waste product
  • To facilitate the release of CO2 into the plasma

    • In the capillary beds, what happens to oxygen?

  • It is released into the plasma
  • It is converted into CO2
  • It is released into the tissues (correct)
  • It is stored in the red blood cells

    • What is the primary route of CO2 transport from the tissues to the lungs?

  • Exclusively via plasma
  • Mostly via plasma and partly via RBC (correct)
  • Mostly via RBC and partly via plasma
  • Exclusively via RBC
