Another example of negative feedback has to do with blood glucose levels. When glucose (sugar) levels in the blood are too high, the pancreas secretes insulin to stimulate the absorption of glucose and the conversion of glucose into glycogen, which is stored in the liver. As blood glucose levels decrease, less insulin is produced. When glucose levels are too low, another hormone called glucagon is produced, which causes the liver to convert glycogen back to glucose.
Jackie and her husband Ken recently had an annual physical with their primary care physician. After they received their lab results, Jackie was told that her blood sugar levels were too high, and Ken was told that his blood sugar levels were too low.
Will Ken's pancreas produce more or less insulin than Jackie's pancreas?
