Allosteric Effects In hemoglobin, allosteric effects occur 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 to minimize oxygen delivery to the tissues for maintaining Fe in the Fe2+ state only in humans ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects The specificity of a ligand binding site on a protein is based on the presence of hydrating water molecules the amino acid residues lining the binding site the opposite chirality of the binding ligand the absence of competing ligands the presence of hydrating water molecules the amino acid residues lining the binding site the opposite chirality of the binding ligand the absence of competing ligands ANSWER DOWNLOAD EXAMIANS APP

Allosteric Effects The conformational changes from the T to the R state is initiated by movement of the F-helix, which contains the proximal His binding of oxygen to the heme reorganization of protein-protein contacts between the individual subunits movement of the proximal histidine towards the heme movement of the F-helix, which contains the proximal His binding of oxygen to the heme reorganization of protein-protein contacts between the individual subunits movement of the proximal histidine towards the heme ANSWER DOWNLOAD EXAMIANS APP
