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 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 movement of the proximal histidine BPG binds to the R state with the same affinity as the T state it is displaced from the heme by oxygen its binding pocket becomes too small to accommodate BPG 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 it is displaced from the heme by oxygen ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects O2 binding to hemoglobin results in both (a) and (b) extensive protein conformational change 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 both (a) and (b) extensive protein conformational change 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
