Answer the following questions based on the figure below: His HC3 B2 His HC3 36. This structural rearrangement originates in the changing conformation of , going from upon A) myoglobin ; folded to unfolded; oxygen release B) heme ; puckered to planar conformation ; oxygen binding ATP ; ATP to ADP : myosin head movement D) the myosin head; straight to bent conformation ; ADP release E) heme ; planar to a puckered conformation; oxygen binding regulation leading to ligand binding 37. This is an example of A) allosteric; independent B) covalent; cooperative C) hydrophobic ; independent D) redox; independent E) allosteric; cooperative 38. This figure shows the structural transitions in going from the on the left to the shown on the right side A) myoglobin ; oxygen-free ; oxygen-bound B) myoglobin ; oxygen-bound ; oxygen-free C) hemoglobin ; T-state ; R-state D) hemoglobin ; R-state T-state E) myosin head ATP-bound; ADP-bound
