Verified step by step guidance

Understand the role of erythrocytes (red blood cells) in the body: Erythrocytes are responsible for transporting oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs.

Identify the key protein involved in oxygen transport within erythrocytes: Hemoglobin is the protein that binds oxygen in the lungs and releases it in the tissues.

Differentiate between the proteins listed: Albumin, Myoglobin, and Fibrinogen. Albumin is a plasma protein that helps maintain osmotic pressure, Myoglobin is an oxygen-binding protein found in muscle tissue, and Fibrinogen is involved in blood clotting.

Focus on Hemoglobin's structure and function: Hemoglobin is composed of four subunits, each containing an iron atom that can bind one molecule of oxygen, allowing each hemoglobin molecule to carry up to four oxygen molecules.

Conclude that Hemoglobin is essential for the transport of oxygen by erythrocytes, as it directly binds and carries oxygen throughout the body.
