How does the beta cell in the pancreas react to release insulin when glucose levels are low?
What will be an ideal response?
ATP dependent potassium gates keep the insulin releasing channels closed when there is enough glucose getting into the cell. When glucose levels drop and the amount of ATP the beta cell is making drops, it eventually loses the energy to keep the gates closed, therefore opening and allowing insulin to be released into the blood.
