Insulin is secreted by the beta cells of the pancreas in response to high blood sugar, although a low level of insulin is always secreted by the pancreas. After a meal, the amount of insulin secreted into the blood increases as the blood glucose rises.lood glucose is normally maintained between 70 mg/dl and 110 mg/dl. Blood glucose levels below 70mg/dl, denote the situation of hypoglycemia. Although blood glucose levels of 110mg/dl can be normal, this is only the case if a meal has been taken within 2 to 3 hours.
Glucose Homeostasis and Starvation. Glucose Homeostasis: the balance of insulin and glucagon to maintain blood glucose. Insulin: secreted by the pancreas in response to elevated blood glucose following a meal.Insulin lowers blood glucose by increasing glucose uptake in muscle and adipose tissue and by promoting glycolysis and glycogenesis in liver and muscle.nsulin: secreted by the pancreas in response to elevated blood glucose following a meal.
