Question

) The pH of the blood declines, amount of oxygen bound to hemoglobin A) Decline B) Increase C) Constant D) None​

Answer 1

The correct option is A) Decline

Explanation:

• The haem of the hemoglobin has a strong binding affinity for oxygen when the pH is normal.
• When the pH declines, the haem of the hemoglobin do not hold the same affinity for oxygen as structural changes occur in it.
• Hence, when the Ph will decline, the affinity for binding and transporting of oxygen by the blood will decline.

Answer 2

Explanation:

The pH of the blood declines, amount of oxygen bound to hemoglobin A) Decline
