Allosteric Effects Bisphosphoglycerate (BPG) cannot bind to the oxygenated R state of hemoglobin because it is displaced from the heme by oxygen it is displaced from the heme by movement of the proximal histidine BPG binds to the R state with the same affinity as the T state its binding pocket becomes too small to accommodate BPG it is displaced from the heme by oxygen it is displaced from the heme by movement of the proximal histidine BPG binds to the R state with the same affinity as the T state its binding pocket becomes too small to accommodate BPG ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects The conformational changes from the T to the R state is initiated by movement of the F-helix, which contains the proximal His binding of oxygen to the heme reorganization of protein-protein contacts between the individual subunits movement of the proximal histidine towards the heme movement of the F-helix, which contains the proximal His binding of oxygen to the heme reorganization of protein-protein contacts between the individual subunits movement of the proximal histidine towards the heme ANSWER DOWNLOAD EXAMIANS APP
