Allosteric Effects An allosteric activator 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 both (a) and (c) ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects The conformational changes from the T to the R state is initiated by movement of the proximal histidine towards the heme reorganization of protein-protein contacts between the individual subunits binding of oxygen to the heme movement of the F-helix, which contains the proximal His movement of the proximal histidine towards the heme reorganization of protein-protein contacts between the individual subunits binding of oxygen to the heme movement of the F-helix, which contains the proximal His ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects O2 binding to hemoglobin results in 100-fold higher affinity for the last O2 bound than for the first extensive protein conformational change 100-fold lower affinity for the last O2 bound than for the first both (a) and (b) 100-fold higher affinity for the last O2 bound than for the first extensive protein conformational change 100-fold lower affinity for the last O2 bound than for the first both (a) and (b) ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects The specificity of a ligand binding site on a protein is based on the opposite chirality of the binding ligand the presence of hydrating water molecules the absence of competing ligands the amino acid residues lining the binding site the opposite chirality of the binding ligand the presence of hydrating water molecules the absence of competing ligands the amino acid residues lining the binding site ANSWER DOWNLOAD EXAMIANS APP
