Allosteric Effects In hemoglobin, allosteric effects occur 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 only in humans 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 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 binding of oxygen to the heme ANSWER DOWNLOAD EXAMIANS APP
Allosteric Effects Small molecules affect hemoglobin (Hb) by increasing [H+] increasing Hb affinity for O2 increasing [H+] and decreasing Hb affinity for O2 decreasing Hb affinity for O2 increasing [H+] increasing Hb affinity for O2 increasing [H+] and decreasing Hb affinity for O2 decreasing Hb affinity for O2 ANSWER DOWNLOAD EXAMIANS APP
