True or False: An increase in pH causes an increase in oxygen dissociation according to the Bohr effect.

The statement is false because, according to the Bohr effect, an increase in pH actually leads to a decrease in oxygen dissociation from hemoglobin. The Bohr effect describes how blood pH affects the affinity of hemoglobin for oxygen. When pH decreases (becomes more acidic), hemoglobin's affinity for oxygen decreases, promoting oxygen release to the tissues. Conversely, an increase in pH (more alkaline) enhances hemoglobin's affinity for oxygen, making it less likely to release oxygen to the tissues. Therefore, the relationship is inversely proportional: as pH rises, oxygen dissociation decreases, which aligns with the principles of the Bohr effect. Understanding this relationship is crucial for exercise physiologists, especially regarding how variations in pH during exercise and metabolism can influence oxygen delivery to the muscles.
