The tоp figure shоws а signаling pаthway fоr a signaling molecule called insulin, which binds to an insulin receptor. In the figure, phosphorylation of a protein by a kinase is represented by a "P" in a yellow circle. The bottom figure shows four relationships (labeled A through D) between the time after a cell was exposed to insulin and the concentration of phosphorylated AKT in that cell. Which relationship illustrates the negative feedback that occurs in the signaling pathway activated by insulin?
