Question

Assertion : in human beings , the respiratory pigment is hemoglobin

Reasoning : it is a type of protein which has high affinity to carbon

dioxide

a) Both the Assertion and the Reason are correct and the Reason is the

correct explanation of the Assertion

b) Both the Assertion and the Reason are correct but the Reason is the

incorrect explanation of the Assertion

c)Our Assertion is true but the Reason is false.

d)The statement of the Assertion is false but the Reason is true​

Answer 1

Answer:

option b is correct because assertion is true respiratory pigment is haemoglobin, and haemoglobin has high affinity with co2 more than o2

Answer 2

Both the Assertion and the Reason are correct but the Reason is the incorrect explanation of the Assertion (option-b).

• Hemoglobin is a red-colored pigment that is present in Red Blood Cells.
• Due to hemoglobin only, RBCs are red in color.
• Hemoglobin is also called respiratory pigment as it carries and transports respiratory gases oxygen and carbon-di-oxide.
• Hemoglobin has more affinity for carbon-di-oxide than oxygen, which means hemoglobin binds more tightly with carbon-di-oxide as compared to oxygen gas.
• Hemoglobin is a type of quaternary protein which is made up of four heteropolymers. Two homopolymers of the alpha unit and two homopolymers of the beta polymer.
• It is composed of globin protein and heme pigment.
