Describe the structure of hemoglobin
WebHemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen. About 6 percent of body iron is a component of certain proteins, essential for respiration and energy metabolism, and as a component of enzymes involved in the synthesis of ... WebHemoglobin carries oxygen from the lungs to the tissues. Myglobin is the oxygen storage protein of the muscle. The richest source of myoglobin is the muscle of aquatic diving mammals, such as seals or whales, since these tissues need a very rich store of oxygen to see them through long anoxic periods during a dive.
