  • where's the narration ... !?!

  • When blood glucose rises, GLUT2

    transporters carry glucose into the β cells

    It is converted to glucose-6-P and

    enters glycolysis, the citric acid cycle

    and oxidative phosphorylation causing the concentration of ATP inside the cell to rise. This rise in ATP closes ATP-gated K+ channelsand the membrane depolarizes; this opens voltage sensitive Ca channels and Ca++ floods in. It's this influx of Ca that triggers fusion of

    the secretory granules with the

    plasma membrane, and insulin release.
