Answer:

In beta cells, insulin release is stimulated primarily by glucose present in the blood. ... Since beta cells use glucokinase to catalyze the first step of glycolysis, metabolism only occurs around physiological blood glucose levels and above. Metabolism of the glucose produces ATP, which increases the ATP to ADP ratio.

Once the glucose has entered the cells, the blood glucose level decreases, and the beta cells stop secreting insulin. ... In one type, the beta cells are destroyed by the immune system and no longer secrete insulin. This is called type I diabetes and is characterized by an absolute deficit of insulin.
