Blood Glucose Regulation: Insulin and Glucagon

This lecture covers the endocrine reflex pathways involved in blood glucose regulation, focusing on the roles of insulin and glucagon. It explains how insulin lowers blood glucose levels by promoting glucose uptake and utilization, while glucagon raises blood glucose levels by stimulating glycogen breakdown and glucose production. The lecture also delves into the molecular mechanisms of insulin secretion, factors influencing insulin release, and the metabolic effects of insulin and glucagon on target cells. Additionally, it discusses the regulation of blood glucose concentration, the insulin signaling pathway, and the responses that alter blood glucose levels, including ingestion of glucose, gluconeogenesis, glycogenolysis, and lipogenesis.
