Bohr effect refers to

Increase of carbon dioxide in the blood and decrease in pH results in the reduction of the affinity of hemoglobin for oxygen.

Alterations in the levels of CO 2 and pH has no effect on the affinity of O 2 with hemoglobin.

Increase in CO 2 and pH in blood results in decrease in the affinity of O 2 with hemoglobin.

Decrease in CO 2 and pH in blood results in an increase in the affinity of O 2 with hemoglobin.

Study the following statements and pick up the correct one:

Decrease in blood pH causes right side shift of oxygen-haemoglobin dissociation curve

Increase in blood pH causes right side shift of the oxygen-haemoglobin dissociation curve

Decreases in temperature causes the right side shift of oxygen-haemoglobin dissociation curve

Increase in CO 2 level in blood causes left side shift of oxygen-haemoglobin curve
