b) Level of glucose increases »» Brain sends message to the pancreas through neurones »» Pancreas releases insulin »» Insulin allows glucose to be taken into cells where is used in respiration. Glucose is also converted to glycogen by liver and muscle which is stored in the liver and muscles »» Levels of blood sugar lowers »» Blood sugar levels return to normal
Level of glucose decreases »» Brain sends message to the pancreas through neurones »» Pancreas releases glucagon »» liver starts to break down stored glycogen and convert it back into glucose which can be used by cells »» Blood sugar levels raise »» Blood sugar levels return to normal
