Questions and Answers

Which of the following statements is true about deoxygenating the unbuffered solution of human oxyhemoglobin in distilled water?

  • As oxygen is released from the protein, the pH of the solution will rise as protons are taken up and bind to the protein.
  • As oxygen is released from the protein, the pH of the solution will fall as protons are taken up and bind to the protein. (correct)
  • As oxygen is released from the protein, the pH of the solution will rise as protons also released from the protein.
  • As oxygen is released from the protein, the pH of the solution will fall as protons also come off the protein.

What happens to the pH of the solution as oxygen is released from the protein in the unbuffered solution of human oxyhemoglobin in distilled water?

  • The pH of the solution will rise as protons are taken up and bind to the protein.
  • The pH of the solution will rise as protons are released from the protein.
  • The pH of the solution will fall as protons also come off the protein. (correct)
  • The pH of the solution will fall as protons are taken up and bind to the protein.

What is the effect of deoxygenating the unbuffered solution of human oxyhemoglobin in distilled water on the pH?
