Question

17. Answer true (T) or false (F) to the following questions about hemoglobin and myoglobin.

a. A drop in the pH of blood plasma from 7.4 to 7.2 will produce a decrease in oxygen affinity for myoglobin and an increase for hemoglobin.

Myoglobin ____

Hemoglobin ____

b. A decrease in the partial pressure of CO₂ in the lungs from 6 kPa (holding one’s breath) to 2 kPa (normal) would produce an increase in oxygen affinity for myoglobin and hemoglobin.

Myoglobin _____

Hemoglobin _____

c. An increase in the in the BPG level from 5mM (normal altitude) to 8 mM (high altitude) would produce a decrease in oxygen affinity for myoglobin and hemoglobin.

Myoglobin __________

Hemoglobin __________

Answer 1

17.a. A drop in the pH of blood plasma from 7.4 to 7.2 will produce a decrease in oxygen affinity for myoglobin and an increase for hemoglobin.

Myoglobin = False

Hemoglobin = False

17. b. A decrease in the partial pressure of CO2 in the lungs from 6 kPa (holding one’s breath) to 2 kPa (normal) would produce an increase in oxygen affinity for myoglobin and hemoglobin.

Myoglobin = False

Hemoglobin = True

17. c. An increase in the in the BPG level from 5mM (normal altitude) to 8 mM (high altitude) would produce a decrease in oxygen affinity for myoglobin and hemoglobin.

Myoglobin = False

Hemoglobin = True
