1What carries oxygen around the body?
Hemoglobin
2What does hemoglobin transport?
Oxygen
3What determines hemoglobin's ability to carry oxygen?
Partial pressure of oxygen
4What affects hemoglobin's oxygen loading?
Partial pressure of oxygen
5What is the Bohr effect?
Effect of CO2 on oxygen unloading
6What is hemoglobin's affinity for oxygen at high CO2?
Low affinity
7What happens to hemoglobin at high partial pressure of oxygen?
Oxygen binds more readily
8What is hemoglobin's behavior in different organisms?
Adapted to environments
9What happens at low oxygen concentration?
Hemoglobin loads oxygen easily
10What does a dissociation curve show?
Hemoglobin saturation at oxygen pressures
11What shape is the dissociation curve?
S-shaped
12What does the S-shape indicate?
Binding and release of oxygen
13Why is the S-shape important?
Shows oxygen loading and unloading
14What does a high partial pressure of oxygen mean?
More oxygen binds to hemoglobin
15What happens when partial pressure of oxygen is low?
Oxygen is released from hemoglobin
16Why do organisms in low-oxygen environments have special hemoglobin?
To load oxygen efficiently
17What curve represents a higher affinity for oxygen?
Curve shifted left
18What curve represents a lower affinity for oxygen?
Curve shifted right
19What do the letters A, B, C, D represent?
Different hemoglobin types in organisms
20Why is hemoglobin adapted for different environments?
To survive in specific conditions
