1

Which phenomenon describes oxygen carriage, and says that CO2 and decreased pH cause the erythrocyte to release oxygen?

Bohr effect

2

Which phenomenon describes CO2 carriage, and says that Oxygen causes the erythrocyte to release CO2

Haldane effect

3

Said another way, which phenomenon states that deoxygenated hemoglobin can carry more CO2?

Haldane effect

4

Carbon dioxide has a unique dissociation curve. And just like before, left is ------ and right is -----.

 

Left is love

Right is release

5

In the presence of oxygenated hemoglobin, the CO2 dissociation curve shifts to the

A. Left

B. Right.

Right

6

In the presence of oxygenated hemoglobin, the CO2 dissociation curve shifts to the right. Hemoglobin has a

A. Decreased affinity for CO2

B. Increased affinity for CO2

Decreased affinity for CO2

7

In the presence of oxygenated hemoglobin, the CO2 dissociation curve shifts to the right. Hemoglobin has a decreased affinity for CO2. This occurs in the

A. Lungs

B. Systemic capillaries

Lungs

8

In the presence of oxygenated hemoglobin, the CO2 dissociation curve shifts to the right. Hemoglobin has a decreased affinity for CO2. This occurs in the lungs to facilitate

A. unloading of CO2 to allow it to be excreted from the body

B. loading of CO2 and its subsequent transport

Unloading of CO2 

to allow it to be excreted from the body

9

In the presence of oxygenated hemoglobin, the CO2 dissociation curve shifts to the right. Hemoglobin has a decreased affinity for CO2. This occurs in the lungs to facilitate the unloading of CO2 to allow it to be

excreted from the body.

10

In the presence of deoxygenated hemoglobin, the CO2 dissociation curve shifts to the

A. Left 

B. Right

Left

11

In the presence of deoxygenated hemoglobin, the CO2 dissociation curve shifts to the left. Hemoglobin has

A. decreased affinity for CO2

B. an increased affinity for CO2

increased affinity for CO2

12

In the presence of deoxygenated hemoglobin, the CO2 dissociation curve shifts to the left. Hemoglobin has an increased affinity for CO2. This occurs in the:

A. Lungs

B. Systemic capillaries

Systemic capillaries

13

In the presence of deoxygenated hemoglobin, the CO2 dissociation curve shifts to the left. Hemoglobin has an increased affinity for CO2. This occurs in the systemic capillaries to facilitate the

A. unloading of CO2 to allow it to be excreted from the body.

B. loading of CO2 and its subsequent transport

Loading of CO2 and its subsequent transport

14

Based on the Haldane Effect and CO2 Dissociation Curve, a lower PO2 means

A. More CO2 is carried

B. Less CO2 is carried

More CO2 is carried

15

Based on the Haldane Effect and CO2 Dissociation Curve, a higher PO2 means

A. More CO2 is carried

B. Less CO2 is carried

Less CO2 is carried
