The protein in haemoglobin is-

Correct option is A

The correct answer is (a) Globin.
· Hemoglobin is a complex protein found in red blood cells that carries oxygen from the lungs to the rest of the body and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is composed of four subunits, each containing a protein part called "globin" and a heme group that binds oxygen. The globin part of hemoglobin is crucial for the structure of the molecule and its ability to transport oxygen effectively.
Information Booster:
· Globulin: A group of proteins in the blood plasma, including antibodies, but not specifically part of hemoglobin.
· Haem: The iron-containing compound in hemoglobin that binds oxygen, but it is not the protein component.
· Albumin: The most abundant protein in blood plasma, responsible for maintaining osmotic pressure, but it is not related to hemoglobin.
