BOHR EFFECT

What is the effect of carbon dioxide on the oxygen affinity of hemoglobin known as?

• The Carbon Dioxide Syndrome

• The Oxygen Paradox

• The Haldane Effect

• The Bohr Effect

How many oxygen molecules can one molecule of hemoglobin bind to?

• Two

• Three

• Four

• Five

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 relationship between hemoglobin and carbon dioxide

• 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

• It shifts the curve downwards

• It shifts the curve to the right

• It shifts the curve upwards

What molecule does carbon dioxide form in the blood?

• Oxygen

• Carbonic acid

• Glucose

• Nitric oxide

What happens to hemoglobin when it combines with a hydrogen ion?

• It increases its affinity for oxygen

• It becomes unable to bind oxygen

• It changes its quaternary structure

• It becomes a carbon dioxide carrier

What is the Bohr effect?

• A decrease in oxygen affinity of hemoglobin as carbon dioxide concentration increases

• An increase in oxygen affinity of hemoglobin as carbon dioxide concentration increases

• A decrease in carbon dioxide affinity of hemoglobin as oxygen concentration increases

• An increase in carbon dioxide affinity of hemoglobin as oxygen concentration increases
