Allosteric Effects In hemoglobin, allosteric effects occur to minimize oxygen delivery to the tissues for maintaining Fe in the Fe2+ state only in humans to maximize oxygen delivery to the tissues to minimize oxygen delivery to the tissues for maintaining Fe in the Fe2+ state only in humans to maximize oxygen delivery to the tissues ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects The specificity of a ligand binding site on a protein is based on 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 the absence of competing ligands ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects Bisphosphoglycerate (BPG) cannot bind to the oxygenated R state of hemoglobin because 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 movement of the proximal histidine it is displaced from the heme by oxygen 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 movement of the proximal histidine it is displaced from the heme by oxygen ANSWER DOWNLOAD EXAMIANS APP
