Allosteric Effects O2 binding to hemoglobin results in extensive protein conformational change both (a) and (b) 100-fold lower affinity for the last O2 bound than for the first 100-fold higher affinity for the last O2 bound than for the first extensive protein conformational change both (a) and (b) 100-fold lower affinity for the last O2 bound than for the first 100-fold higher 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 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 BPG binds to the R state with the same affinity as the T state ANSWER DOWNLOAD EXAMIANS APP

Allosteric Effects A protein that binds two ligands in a non-cooperative manner will show both (b) and (c) a linear Scatchard Plot a hyperbolic binding curve a sigmodial binding curve both (b) and (c) a linear Scatchard Plot a hyperbolic binding curve a sigmodial binding curve ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects The conformational changes from the T to the R state is initiated by binding of oxygen to the heme reorganization of protein-protein contacts between the individual subunits movement of the F-helix, which contains the proximal His movement of the proximal histidine towards the heme binding of oxygen to the heme reorganization of protein-protein contacts between the individual subunits movement of the F-helix, which contains the proximal His movement of the proximal histidine towards the heme ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects In hemoglobin, allosteric effects occur only in humans to minimize oxygen delivery to the tissues to maximize oxygen delivery to the tissues for maintaining Fe in the Fe2+ state only in humans to minimize oxygen delivery to the tissues to maximize oxygen delivery to the tissues for maintaining Fe in the Fe2+ state ANSWER DOWNLOAD EXAMIANS APP
