Specific dynamic action (SDA), also known as the thermic effect of food (TEF) or dietary induced thermogenesis (DIT), is the increase in metabolic rate that occurs after eating. It is the energy that is required to digest, absorb, and transport food molecules into the cells and tissues of the body.
Mechanism of Action of Insulin Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood glucose levels. Here’s how it works: Glucose Absorption: When carbohydrates are consumed, body breaks them down into glucose, a simple sugar that serves as a vital energy source. (a) Insulin attaches to insulin receptors of the target cell. (b) Activates a cascade of signaling leading to the formation of certain protein called GLUT4 which is a glucose transporter protein, (c) GLUT4 is then translocated to the Plasma membrane and Transport glucose into the cell. (d) Inside the cell Glucose converted to Glucose-6-phosphate which is used as a source of energy. - In that way the glucose absorption pathway is regulated by the action of Insulin.
