Chapter 25, Problem 7SQ
Summary Introduction
Concept introduction: Insulin hormone originated in the body from pancreas. Insulin is a regulatory hormone that helps the body to convert blood sugar into energy. The increase in blood sugar stimulates the pancreas to release insulin into the blood stream. Without insulin, the body does not use or store glucose for energy as it stays in our blood and causes diabetes.
