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