| Question |
Answer |
| How much O2 does Plasma transport? |
<2% |
| How much O2 does Hemoglobin transport? |
98% |
| How many O2 molecules can Hemoglobin carry and at what % saturation? |
4 @ 100% saturation = Oxyhemoglobin |
| How much O2 is unloaded at the tissues? |
20% |
| How does LOW PO2 effect HgbO2 dissociation? |
Lower PO2 --> LESS O2 affinity (INCREASE release of O2) |
| How does a HIGH pH effect HgbO2 dissociation? |
HIGIH acidity --> LESS O2 affinity --> (INCREASE release of O2) |
| How does a LOW pH effect HgbO2 dissociation? |
LOW acidity --> HIGHER O2 affinity |
| How does HIGH Temperature effect HgbO2 dissociation? |
HIGH Temp. --> LESS O2 affinity (INCREASE release of O2) |
| How does LOW Temperature effect HgbO2 dissociation? |
LOW Temp. --> HIGH O2 affinity |
| What does affinity mean? |
Hold |
| Which 2 influences on HgbO2 dissociation effect protein shape? |
pH, Temp. |
| How much CO2 is carried in Plasma? |
CO2 <--dissolved --> <10% |
| How much CO2 is carried in RBC as Carbamaminohemoglobin? |
CO2 <-->reduced Hb <--> HbCO2 (30%) |
| How much CO2 is carried in RBC as Carbonic Acid? |
CO2 + H2O <--> H2CO3 <--> H+ + HCO3- (60%) |
