Question:
The Bohr effect describes:
The Bohr effect describes:
Show Hint
In the Bohr effect, lower pH and increased CO$_2$ concentration result in decreased hemoglobin affinity for O$_2$, promoting oxygen release.
Updated On: Jun 18, 2025
- Increased O$_2$ affinity of hemoglobin at low pH
- Decreased O$_2$ affinity of hemoglobin at low pH
- Cooperative binding of O$_2$ to hemoglobin
- Allosteric inhibition of hemoglobin by CO$_2$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The Bohr effect explains how hemoglobin's affinity for oxygen decreases at lower pH, which helps facilitate oxygen release in tissues that are actively metabolizing and producing acidic byproducts, like CO$_2$. This decrease in affinity allows for more efficient oxygen delivery to those tissues.
