Allosteric Effects Small molecules affect hemoglobin (Hb) by increasing [H+] increasing Hb affinity for O2 increasing [H+] and decreasing Hb affinity for O2 decreasing Hb affinity for O2 increasing [H+] increasing Hb affinity for O2 increasing [H+] and decreasing Hb affinity for O2 decreasing Hb affinity for O2 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 absence of competing ligands the presence of hydrating water molecules the opposite chirality of the binding ligand the amino acid residues lining the binding site the absence of competing ligands the presence of hydrating water molecules the opposite chirality of the binding ligand ANSWER DOWNLOAD EXAMIANS APP
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 O2 binding to hemoglobin results in extensive protein conformational change 100-fold higher affinity for the last O2 bound than for the first both (a) and (b) 100-fold lower affinity for the last O2 bound than for the first extensive protein conformational change 100-fold higher affinity for the last O2 bound than for the first both (a) and (b) 100-fold lower affinity for the last O2 bound than for the first 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 it is displaced from the heme by oxygen it is displaced from the heme by movement of the proximal histidine 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 oxygen it is displaced from the heme by movement of the proximal histidine its binding pocket becomes too small to accommodate BPG ANSWER DOWNLOAD EXAMIANS APP
