In the Bohr effect, protonation of the imidazolium rings of the C-terminal rings of the C-terminal residues (His 126B) of the hemoglobin's two B chains is responsible for around 40% of the .60 mole of H+ that combine with Hb on the release of 1.00 mole of O2 at pH 7.40. Assuming that this imidazolium group has pKa = 7.10 in R-state oxyHb, what is its pKa value in T-state deoxyHb? (Hint: the pH of the blood - because it's...

1. Describe using thermodynamics the enthalpic stabilizatiok of the T-state and whether high or low [O2] would be favored and why. 2. Predict the effect of red blood cells expressing (producing) myoglobin instead of hemoglobin. 3. List the interactions that stabilize the R-state (oxyhemoglobin), pick all that are correct. A) Numerous salt bridge interactions in the central cavity B) Coordinate covalent bonds (4) between O2 and heme C) H-bonding (4) between O2 and distal His 4. Where are the interactions...

For the video response portion of this assignment, your job will be to state what would happen to the oxygen bond to Hemoglobin if the pH of the tissue was the same as that of the lungs using the logic of the person’s presentation you watched. Discuss whether or not you agree with this. The video said this: Oxygen must be transported in the blood from the lungs, because the partial pressure of oxygen (pO2) is relatively high (approximately 100...

Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...
