Feedback loop in glucose

Submitted by kheredia on Tue, 10/15/2019 - 17:25

Feedback loops typically include a sensor, control sensor, and an effector which executes the change in the body to return back to homeostasis


How normal feedback loop for blood glucose goes:

  1. we eat sugar, blood glucose rises

  2. Sensor; pancreatic beta cells sense this and release vesicle stored insulin

  3. control center; pancreatic beta cells (still) - insulin travels to bloodstream to fat and skeletal muscle

  4. effector: fat and skeletal muscle - stores glucose. has insulin receptors which bind to insulin when it arrives. GLUT 4 (glucose transporters) are signaled to enter plasma membrane to bring glucose via facilitated diffusion back into the cell

  5. result: blood glucose levels fall back down
