The flashcards below were created by user lcunrod7 on FreezingBlue Flashcards. What would you like to do?


  1. what are the two methods of transport of oxygen
    dissolved O2 and bound to Hb
  2. what method is in plasma ~1.5%
    dissolved O2
  3. what method is bound to iron in center of heme, 98.5% carried this way, "oxyhemoglobin"
    boung to Hb
  4. what % of heme units that contain O2 at any given moment
    hemoglobin saturation
  5. what is a very small change in the Po2 results in big change in the ability of Hb to bind O2 (or release O2)
    steep slope
  6. what are the two factors which affect how much O2 binds to Hb
    Ph and temperature
  7. when there is and increase curve "shifts" left Hb wants to release less O2
    Ph
  8. when there is a decrease curve "shifts" right Hb wants to release more O2
    pH
  9. 20C decrease Hb release less O2
    temperature
  10. 40C increase Hb release more O2
    temperature
  11. what by product of glycolysis (make ATP) reaction in RBC's,
    BPG production
  12. increase BPG = increase release of O2 by Hb
    BPG production
  13. what is a by product of aerobic metabolism in peripheral tissues
    CO2
  14. what are the methods of CO2 transport
    carbonic acid 70% , bound to globular protein subunits of Hb 23%, dissolved in plasma 7%
  15. what is in red blood cells, CO2—> carbonic anhydrase —> carbonic acid (H2CO3) —> H+(hydrogen ion) plus HCO3- (bicarbonate ion)
    carbonic acid
  16. what has carbaminohemoglobin  (HbCO2)
    bound to globular protein subunits of Hb
