Oxygen-carrying capacity

Definition

Oxygen-carrying capacity is the maximum amount of oxygen that can be transported by hemoglobin in the blood. It is crucial for efficient cellular respiration and overall metabolic function.

5 Must Know Facts For Your Next Test

1. Hemoglobin is the primary protein responsible for oxygen transport in the blood.
2. Each hemoglobin molecule can bind up to four oxygen molecules.
3. Oxygen-carrying capacity is influenced by factors such as hemoglobin concentration, partial pressure of oxygen, and pH levels.
4. A decrease in oxygen-carrying capacity can lead to conditions like anemia and hypoxia.
5. The Bohr effect describes how changes in carbon dioxide concentration and pH affect hemoglobin's affinity for oxygen.
