What is the Bohr effect in the transport of carbon dioxide in human blood?
The release of oxygen from hemoglobin when carbon dioxide levels are high
The release of carbon dioxide from bicarbonate ions when pH is low
The binding of carbon dioxide to hemoglobin in the lung
The binding of bicarbonate ions to hemoglobin in the tissues
The release of oxygen from hemoglobin when carbon dioxide levels are high
Explanation: The Bohr effect is a phenomenon in which the affinity of hemoglobin for oxygen decreases in the presence of an increase in carbon dioxide or a decrease in pH. In other words, when there is an increase in carbon dioxide or a decrease in pH, hemoglobin is less able to bind to oxygen, which causes the release of oxygen to the surrounding tissues. This effect occurs because carbon dioxide reacts with water to form carbonic acid, which lowers the pH of the blood. The Bohr effect plays an important role in the transport of oxygen and carbon dioxide in the blood, as it helps to ensure that oxygen is released from hemoglobin in the tissues where it is needed most. It is named after the Danish physiologist Christian Bohr who first described the effect in 1904.
