The reason that athletes often move to elevations higher than those, at which they will compete, several months before a competition. Introduction: Red blood cells (RBCs) play an important role in the body of an organism. They carry oxygen from lungs to different tissues. RBC is produced in red bone marrow and each has a lifespan of 120 days. The level of hemoglobin or number of RBCs determines the oxygen transport to the tissues. Hemoglobin is a globular protein, which contains two alpha chains, two beta chains, and a nonprotein pigment called heme. There are four heme units in one hemoglobin molecule and each heme unit can hold an iron, which binds to an oxygen molecule.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
