Assertion: Hemoglobin plays a critical role in the transport of carbon dioxide in the blood.
Reason: Hemoglobin can bind with CO2 to form carbamino compounds.
Mark the correct choice as:
If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
If Assertion is true but Reason is false.
If both Assertion and Reason are false.
Hemoglobin can bind with CO2 to form carbamino compounds, which can be transported in the blood. This mechanism is one of the ways that CO2 is transported from the tissues to the lungs for elimination. Hence, option 1 is the correct answer.
