Final answer:
True, oxygen binding to hemoglobin results in the formation of oxyhemoglobin. This process is crucial for oxygen transport from the lungs to other parts of the body, following a reversible reaction and a characteristic oxygen dissociation curve.
Step-by-step explanation:
True, when oxygen is bound to hemoglobin it becomes oxyhemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues to the lungs. In the lungs, oxygen binds to the iron ions within the hemoglobin molecule, forming oxyhemoglobin, a bright red molecule, which transforms back to reduced hemoglobin as it releases oxygen into body tissues.
The process of oxygen binding to hemoglobin is reversible and can be represented by the equation: Hb + O₂ → HbO₂. It's important to note that oxygen binding to hemoglobin follows a sigmoidal dissociation curve, with increased oxygen binding efficiency after the first oxygen molecule is bound. Increased oxygen saturation in hemoglobin occurs with increased partial pressure of oxygen. This association facilitates the transport of oxygen throughout the body.
