- Q1to carry oxygen from gas exchange to tissue that need it for aerobic respirationwhat is the role of the haemoglobin in the blood30s
- Q2complex protein with a quaternary structure with 4 haem groups that can carry 4 oxygenswhat does Haemoglobin have that makes it a unique protein30s
- Q3the amount of oxygen combined is put over 4 per Hb moleculewhat is % saturation30s
- Q4a measurement of the concentration of oxygen in the bloodpartial pressure of oxygen30s
- Q5highest saturation and highest PPO2what do lungs have in terms of saturation and PPO230s
- Q6lowest saturation and lowest PPO2what do cells have in terms of saturation and PPO230s
- Q7oxyhaemoglobin releases o2 at the respiring tissuesdissociate30s
- Q8oxyhaemoglobin formed in the lungsassociates30s
- Q9strength of attraction of o2 is low to Hblow affinity30s
- Q10strength of attraction of o2 is high to Hbhigh affinity30s
- Q11low levels of o2 in the bloodlow PPO230s
- Q12high levels of o2 in the bloodhigh PPO230s
- Q13mutations occur in the amino acid sequence in different animals to favour their rate of respirationwhy are there different Hb30s
- Q14% saturation against PPO2 with a sigmoid shapewhat does the oxygen saturation curve show30s
- Q15species that live in low PPO2 so Hb has a higher affinity for it becoming fully saturatedif the oxygen saturation curve has moved to the left, what does it show about the Hb30s
