Oxygen Transportation Quiz

What is the main protein responsible for oxygen transportation in the blood?

• myoglobin

• hemoglobin

• collagen

• keratin

Which cells in the blood are responsible for carrying oxygen?

• Red blood cells

• Platelets

• White blood cells

• Plasma

What is the term used to describe the relationship between oxygen saturation and partial pressure of oxygen?

• oxygen binding curve

• oxygen affinity curve

• oxygen saturation curve

• oxygen dissociation curve

What is the normal range of oxygen saturation in arterial blood?

• 80% - 85%

• 90% - 95%

• 95% - 100%

• 105% - 110%

What is the term used to describe the difference in oxygen content between arterial and venous blood?

• oxygen saturation difference

• blood oxygenation discrepancy

• venous-arterial oxygen difference

• arteriovenous oxygen difference

What is the Bohr shift?

• The Bohr shift is the increase in hemoglobin's affinity for oxygen due to increased carbon dioxide levels.

• The Bohr shift is the decrease in hemoglobin's affinity for oxygen due to decreased carbon dioxide levels.

• The Bohr shift is the increase in hemoglobin's affinity for carbon dioxide due to increased oxygen levels.

• The Bohr shift is the decrease in hemoglobin's affinity for oxygen due to increased carbon dioxide levels.

What causes the Bohr shift in the oxygen dissociation curve?

• Increase in carbon dioxide (CO2) and increase in pH (acidic conditions).

• Increase in carbon dioxide (CO2) and decrease in pH (acidic conditions)

• Decrease in carbon dioxide (CO2) and decrease in pH (alkaline conditions).

• Decrease in carbon dioxide (CO2) and increase in pH (alkaline conditions).

What is the effect of the Bohr shift on oxygen affinity?

• Remain the same

• Increase

• Decrease

• Fluctuate

How does the Bohr shift affect oxygen unloading in tissues?

• The Bohr shift increases the affinity of hemoglobin for oxygen, inhibiting oxygen unloading in tissues.

• The Bohr shift has no effect on oxygen unloading in tissues.

• The Bohr shift increases the concentration of oxygen in tissues, promoting oxygen unloading.

• The Bohr shift decreases the affinity of hemoglobin for oxygen, facilitating oxygen unloading in tissues.
