BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Hemoglobin is the protein that transports oxygen (O2) in human blood from the lungs to the tissues of the body. Proteins are formed by the linking of amino acids into polypeptide chains.

Detailed explanation-2: -Hemoglobin is the protein that makes blood red. It is composed of four protein chains, two alpha chains and two beta chains, each with a ring-like heme group containing an iron atom. Oxygen binds reversibly to these iron atoms and is transported through blood.

Detailed explanation-3: -You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells. It’s the hemoglobin that gives red blood cells their color, too.

Detailed explanation-4: -RBCs contain hemoglobin (pronounced: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.

Detailed explanation-5: -Hemoglobin and myoglobin both are the transport proteins, Hemoglobin transportation:-It carries oxygen from the lungs to the rest of the body and a portion of carbon dioxide in the opposite direction.
