What is the effect of a decrease in Ph on the oxygen-carrying capacity of hemoglobin?
Correct answer: C. Negative
- A. Positive
- B. No effect
- C. Negative
- D. First negative then positive
Explanation
When the solution is at a lower pH, hemoglobin tends to release more oxygen because it doesn't have as much affinity to keep the oxygen bonded to the heme group. So the oxygen-carrying capacity of the hemoglobin will decrease if human blood becomes acidic.
