Cells use upregulation to increase their sensitivity to a specific hormone. Doctors may also use glucagon when diagnosing problems with the digestive system. The time it takes to fully replenish glycogen stores can depend on how hard and how long we exercise and can vary from a few hours to several days. Energy can be stored by the body in different forms. However, there is a bit more to it than that., Healthy individuals release insulin throughout the day in small quantities to constantly keep their glucose in that tight range mentioned earlier.
