Allosteric Effects Bisphosphoglycerate (BPG) cannot bind to the oxygenated R state of hemoglobin because it is displaced from the heme by movement of the proximal histidine it is displaced from the heme by oxygen its binding pocket becomes too small to accommodate BPG 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 it is displaced from the heme by oxygen its binding pocket becomes too small to accommodate BPG BPG binds to the R state with the same affinity as the T state ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects The specificity of a ligand binding site on a protein is based on the absence of competing ligands the opposite chirality of the binding ligand the presence of hydrating water molecules the amino acid residues lining the binding site the absence of competing ligands the opposite chirality of the binding ligand the presence of hydrating water molecules the amino acid residues lining the binding site ANSWER DOWNLOAD EXAMIANS APP
