The pathway above illustrates the role of insulin in the regulation of glucose in the blood. When blood sugar (glucose) levels a
re elevated, insulin is released to trigger cells to take in glucose. Although insulin never enters the cell, it creates a signaling cascade that mobilizes Glut-4 transporters to the surface of the cell. What describes the movement of glucose into the cell using Glut-4 transporters?
Facilitate diffusion describes the movement of glucose into the cell using Glut-4 transporters.
Explanation:
Glut-4 transporter benolgs the family of carrier proteins that helps in the uptake of glucose by the cell mediated by the action of insulin hormone.
The binding of insuin to its receptors signals the movement of glut-4 transporter from the interior of the cell to cell surface.After reaching the cell surface glut-4 proteins binds to the glucose molecule and then undergo Conformational change to deliver those glucose molecules inside the target cell.
