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
