Detailed explanation-1: -As you note, Fe2+ has an oxidation potential of −0.77V, meaning it is a less powerful reducing agent than hydrogen gas.
Detailed explanation-2: -Iron is a part of hemoglobin, a protein that transports oxygen from the lungs to the tissues. It helps provide oxygen to muscles. Iron is important for cell growth, development, and normal body functions. Iron also helps the body make some hormones and connective tissue.
Detailed explanation-3: -Iron is an essential element for almost all living organisms as it participates in a wide variety of metabolic processes, including oxygen transport, deoxyribonucleic acid (DNA) synthesis, and electron transport.
Detailed explanation-4: -The core of ferritin isolated from tissues contains Fe3+, but Fe2+ is required for experimental core formation in protein coats; reduction of Fe3+ to Fe2+ facilitates iron removal from protein coats.
