Question: 1 / 400

What is hemoglobin primarily responsible for?

Binding to carbon dioxide in tissues

Transporting nutrients to cells

Binding to oxygen in red blood cells

Hemoglobin is primarily responsible for binding to oxygen in red blood cells. This protein, found in the erythrocytes (red blood cells), plays a crucial role in the respiratory process by picking up oxygen from the lungs and transporting it to tissues throughout the body where it can be utilized for cellular respiration and energy production. The ability of hemoglobin to bind oxygen is essential for maintaining adequate oxygen levels in the bloodstream, which is vital for the survival of tissues and organs.

While hemoglobin does interact with carbon dioxide, transporting it from tissues back to the lungs for exhalation, its primary and most critical function is the transport of oxygen. It does not transport nutrients directly to cells or facilitate blood clotting processes, which are functions associated with different components of blood and other proteins.
