WebStudy with Quizlet and memorize flashcards containing terms like planar heme group, relaxed state, high pH, subunits are closer together -When hemoglobin binds oxygen, it is in the R-state and heme is the planar conformation. Hemoglobin binds oxygen in the lungs, where the pH is high., CO2 decreases from exhalation, thus the pH of the lungs … Hemoglobin has a quaternary structure characteristic of many multi-subunit globular proteins. Most of the amino acids in hemoglobin form alpha helices, and these helices are connected by short non-helical segments. Hydrogen bonds stabilize the helical sections inside this protein, causing attractions within the molecule, which then causes each polypeptide chain to fold into a specific sha…
