Sigmoid

Vedclass · Answer

(A) The oxygen dissociation curve of hemoglobin is $S$-shaped,which is technically referred to as a $Sigmoid$ curve. This shape occurs because the binding of one molecule of $O_2$ to hemoglobin increases the affinity of the remaining heme groups for $O_2$,a phenomenon known as cooperative binding. As the partial pressure of oxygen $(pO_2)$ increases,the percentage saturation of hemoglobin with oxygen increases,resulting in this characteristic $Sigmoid$ pattern.
