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 reorganization of protein-protein contacts between the individual subunits movement of the proximal histidine towards the heme binding of oxygen to the heme movement of the F-helix, which contains the proximal His reorganization of protein-protein contacts between the individual subunits movement of the proximal histidine towards the heme binding of oxygen to the heme ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects Bisphosphoglycerate (BPG) cannot bind to the oxygenated R state of hemoglobin because 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 it is displaced from the heme by oxygen it is displaced from the heme by movement of the proximal histidine ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects In hemoglobin, allosteric effects occur 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 to minimize oxygen delivery to the tissues for maintaining Fe in the Fe2+ state ANSWER DOWNLOAD EXAMIANS APP
