What does the oxygen dissociation curve represent?

• The amount of oxygen needed for aerobic respiration

• The percentage saturation of hemoglobin with oxygen against its partial pressure

• The lifespan of a red blood cell

What happens to the affinity of hemoglobin for oxygen as the partial pressure of oxygen decreases?

• It remains constant

• It increases

• It decreases

• It fluctuates unpredictably

What is the oxygen saturation level of hemoglobin in the alveoli?

• Around 97%

• Around 100%

• Around 85%

• Around 75%

What effect does the unloading of one oxygen molecule have on hemoglobin?

• It increases the affinity for oxygen

• It doubles the affinity for oxygen

• It does not change the affinity for oxygen

• It reduces the affinity for oxygen

How does the presence of carbon dioxide affect the oxygen dissociation curve?

• It shifts the curve to the left
