6 Insulin action. Much more than glucose uptake! Muscle: Increase glucose uptake GLUT4 translocation & blood flow Increase glycogen synthesis Increased protein synthesis + proteolysis Increased potassium uptake Stimulation of uptake of ketone bodies

7 Insulin action. Much more than glucose uptake! Liver: Decreased glucose output, due to: Decreased gluconeogenesis + increased glycogen synthesis Decreased formation of ketone bodies Increased lipid synthesis Re-esterification of FFA with glycerol phosphate (from glycolysis or glycerol) Stimulation of enzymes involved in lipid synthesis (Acetyl-CoA carboxylase + fatty acid synthase) Indirectly by increased Manolyl CoA which inhibits Carnitine acyltransferase) Increased protein synthesis + proteolysis

8 Insulin action. Much more than glucose uptake! Adipose tissue: Increased glucose uptake Inhibition of lipolysis Hormone Sensitive Lipase inhibition Stimulation of lipoprotein lipase (in capillaries around adipocytes) Hydrolyses the triglyceride that resides in e.g. VLDL and chylomicrons to FFA and monoacylglycerol. FFA is then taken up by the adipocytes. Increases potassium uptake
