Question

Quizplus · Accepted Answer

Red blood cells are specialized cells that transport oxygen from the lungs to the different cells and tissues of the body. Oxygen is bound to the protein hemoglobin present in the red blood cells, forming a molecule called oxyhemoglobin. This molecule is responsible for the transport of oxygen from the lungs to the tissues, where the oxygen is released and used by cells for energy production. Carbon dioxide is also transported by red blood cells, but it is bound to a different site on the hemoglobin molecule. Therefore, the best choice is A, oxygen/hemoglobin.
