The Role of Insulin and Glycogen in Blood Glucose Control and Diabetes

The video discusses the roles of insulin and glycogen in regulating blood glucose levels through negative feedback cycles. Insulin lowers blood glucose by promoting glucose uptake and storage as glycogen, while glycogen increases blood glucose by converting stored glycogen back to glucose. The video also covers diabetes, highlighting type 1 diabetes as a condition where the pancreas fails to produce enough insulin, and type 2 diabetes where the body becomes resistant to insulin. Management strategies for type 2 diabetes include diet, exercise, and medication.
