Allosteric Effects The specificity of a ligand binding site on a protein is based on the absence of competing ligands the amino acid residues lining the binding site the presence of hydrating water molecules the opposite chirality of the binding ligand the absence of competing ligands the amino acid residues lining the binding site the presence of hydrating water molecules the opposite chirality of the binding ligand ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects An allosteric activator both (a) and (c) increases the binding affinity decreases the binding affinity stabilizes the R state of the protein both (a) and (c) increases the binding affinity decreases the binding affinity stabilizes the R state of the protein ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects Bisphosphoglycerate (BPG) cannot bind to the oxygenated R state of hemoglobin because its binding pocket becomes too small to accommodate BPG 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 it is displaced from the heme by oxygen its binding pocket becomes too small to accommodate BPG 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 it is displaced from the heme by oxygen ANSWER DOWNLOAD EXAMIANS APP
