Allosteric Effects O2 binding to hemoglobin results in 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 extensive protein conformational change 100-fold higher affinity for the last O2 bound than for the first both (a) and (b) ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects An allosteric activator stabilizes the R state of the protein decreases the binding affinity both (a) and (c) increases the binding affinity stabilizes the R state of the protein decreases the binding affinity both (a) and (c) increases the binding affinity 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
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 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 movement of the F-helix, which contains the proximal His ANSWER DOWNLOAD EXAMIANS APP
