Bohr Effect
About the Lecture
The lecture Bohr Effect by Kevin Ahern, PhD is from the course Amino Acid Metabolism.
Included Quiz Questions
In the Bohr effect, which of the following is true of hemoglobin?
- It has a greater affinity for oxygen at higher pH.
- It releases carbon dioxide when it binds to protons.
- It lets go of oxygen as the proton concentration decreases.
- It has a greater affinity for oxygen at lower pH.
- Protons have no effect on hemoglobin's shape.
In the Bohr effect, hemoglobin releases which of the following?
- Additional oxygen near rapidly metabolizing tissues
- Additional carbon dioxide in the presence of oxygen.
- Additional oxygen in the presence of oxygen and carbon dioxide
- Additional oxygen in the presence of oxygen
- Additional carbon dioxide in the presence of protons
Which of the following do not affect hemoglobin’s affinity for oxygen? (Check all that apply)
- Nitrogen concentration
- Na+ ion concentration
- Proton concentration
- Oxygen concentration
- Carbon dioxide concentration
How does the proton concentration affect the affinity of hemoglobin for oxygen?
- Protons bind to hemoglobin, lowering the affinity for oxygen.
- Protons change the amino acid sequence of hemoglobin, lowering its affinity for oxygen.
- Protons bind to hemoglobin, increasing its affinity for oxygen.
- Protons change the amino acid sequence of hemoglobin, increasing its affinity for oxygen.
- Protons allow more carbon dioxide in the blood, increasing hemoglobin's affinity for oxygen,
