Directions : In the following question, the Assertions (A) and Reason...
Assertion: Haemoglobin has quaternary structure.
Reason: Haemoglobin has four chains, two α-chains and two β-chains.
Explanation:
The quaternary structure of a protein refers to its arrangement of multiple protein subunits. In the case of hemoglobin, it is composed of four protein chains, two α-chains, and two β-chains. Each chain is associated with a heme group, which contains an iron atom that binds to oxygen.
Quaternary Structure of Hemoglobin:
Hemoglobin is a globular protein found in red blood cells and is responsible for transporting oxygen throughout the body. It consists of four subunits arranged in a quaternary structure. These subunits are designated as α1, α2, β1, and β2.
Reasoning:
The reason provided, stating that hemoglobin has four chains, two α-chains, and two β-chains, supports the assertion that hemoglobin has a quaternary structure. The quaternary structure of hemoglobin arises from the association of these four protein chains. Each chain contributes to the overall structure and function of the protein.
Importance of Quaternary Structure:
The quaternary structure of hemoglobin is crucial for its function. The four subunits come together to form a functional hemoglobin molecule, which can bind and transport oxygen. The association of the α-chains and β-chains is necessary for the proper folding and stability of the protein. Any disruption in the quaternary structure of hemoglobin can lead to functional abnormalities, such as sickle cell anemia.
Conclusion:
Both the assertion and reason are true. The reason correctly explains why the assertion is true. Hemoglobin indeed has a quaternary structure due to the presence of four protein chains, two α-chains, and two β-chains. This quaternary structure is vital for the proper functioning of hemoglobin in oxygen transport.
