Allosteric Effects O2 binding to hemoglobin results in 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 extensive protein conformational change ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects The conformational changes from the T to the R state is initiated by reorganization of protein-protein contacts between the individual subunits binding of oxygen to the heme movement of the proximal histidine towards the heme movement of the F-helix, which contains the proximal His reorganization of protein-protein contacts between the individual subunits binding of oxygen to the heme movement of the proximal histidine towards the heme movement of the F-helix, which contains the proximal His 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 it is displaced from the heme by oxygen it is displaced from the heme by movement of the proximal histidine BPG binds to the R state with the same affinity as the T state its binding pocket becomes too small to accommodate BPG it is displaced from the heme by oxygen it is displaced from the heme by movement of the proximal histidine BPG binds to the R state with the same affinity as the T state ANSWER DOWNLOAD EXAMIANS APP
