Detailed explanation-1: -Hemoglobin (Heme + Globin) The protein hemoglobin is a molecule which is responsible for carrying almost all of the oxygen in the blood. It is composed of four subunits, each with a heme group plus a globin chain.
Detailed explanation-2: -Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
Detailed explanation-3: -Hemoglobin is a protein found in red blood cells. It contains iron, which allows it to transport oxygen. Each hemoglobin molecule can bind up to four oxygen molecules. This way, it can transport the oxygen from the lungs to the tissues that need it.
Detailed explanation-4: -Haemoglobin molecules inside red blood cells pick up and carry the oxygen. These oxygen-rich cells travel in the blood vessels from the lungs to the left side of the heart. The blood is then pumped around the body. Red blood cells are adapted for the transport of oxygen.
Detailed explanation-5: -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.
