How does the body typically respond to low blood sugar?

When blood sugar levels fall, the body initiates a series of physiological responses to restore them to normal levels. One key mechanism is the release of glucose from glycogen stored in the liver, a process known as glycogenolysis. The liver breaks down glycogen into glucose and releases it into the bloodstream, thereby increasing blood sugar levels to provide the necessary energy for the body.

The other presented options do not accurately reflect the body's response to low blood sugar. For instance, an increase in insulin release would actually lower blood sugar levels, as insulin facilitates glucose uptake by cells. Inhibition of glucagon secretion would also not make sense because glucagon is critical in raising blood sugar by promoting glycogen breakdown. Lastly, dehydration of body cells is not a direct response to low blood sugar; rather, dehydration may lead to other metabolic issues but is not a primary response to hypoglycemia. Thus, the correct choice highlights the essential role of glycogen mobilization in correcting hypoglycemia.
