Gas Transport Flashcards
1
Q
How is oxygen transported in the blood?
A
- 98.5% is transported by binding to hemoglobin
-1.5% is transported by dissolving into plasma
2
Q
What is deoxyhemoglobin?
A
hemoglobin that does not have oxygen bound to it
3
Q
What is carbonic anhydrase?
A
an enzyme that catalyzes the reversible reaction between carbon dioxide and water to form carbonic acid
4
Q
3 ways carbon dioxide is transported in the blood and percentage transported
A
carbonic acid: 70%
carbamino compounds: 23%
dissolved gas: 7%
5
Q
What is the haldane effect?
A
deoxygenated blood can carry more CO₂ than oxygenated blood
6
Q
Haldane effect role in CO2
A
promotes CO₂ uptake in the tissues and CO₂ release in the lungs
7
Q
Define oxygen affinity
A
how strongly hemoglobin binds to oxygen
