Insulin, Exercise & Plasma Glucose
This podcast from the "Metabolism Made Easy" channel **describes the body's response to food intake**, focusing on **how blood glucose and insulin levels interact**. After a meal, **blood glucose rises, prompting the pancreas to release insulin**. Insulin then **facilitates glucose uptake into muscle and fat cells** and **promotes glucose storage as glycogen in the liver and muscles**, ultimately **lowering blood glucose**. The video explains that **insulin increases glucose transporters (GLUT4) on muscle and adipose tissue**, enabling efficient glucose absorption by those tissues specifically. Furthermore, it highlights how **moderate exercise can enhance muscle glucose consumption**, suggesting that **combining insulin's effects with physical activity helps prevent post-meal blood glucose spikes** and **maintains stable blood sugar levels**.
