OCR A2 F214 4.1.3 HORMONES- insulin regulation

Key outline about how insulin levels is regulated  with reference to potassium, sodium and calcium channels 

All of the steps are clear,simple and checked bt teachers

Enjoy and rate me 5/5 :)

  • F214 REGULATION OF INSULIN LEVELS
    • 1. The cell membrane of the beta cells contain both calcium and potassium channels
      • 2. K iion channels ate normally open. so Ca ions channels are closed. K ions diffuse from the inside to ouside of the cell freely, making the inside of the cell -ve with respect to the ouside
        • 3. When  the glucose concentration outside of the cell is high, glucose molecules diffuse into the cell
