Question

Quizplus · Accepted Answer

The main benefit of hemoglobin in the blood is that it increases the amount of oxygen that can be carried in the blood. Hemoglobin is a protein found in red blood cells that binds to oxygen and transports it from the lungs to the tissues of the body. This is essential for cellular respiration, which is the process by which cells produce energy in the form of ATP. Without hemoglobin, the body would not be able to transport enough oxygen to support cellular respiration, which would result in cell death and eventually organ failure.
