Effects of insulin in adipose tissue

Answer 19

increase lipoprotein lipase activity - reduced TGs
Increase GLUT-4 activity and raised glucose storage as fat
reduced lipolysis - reduce fatty acids released into circulation

Reduced glycogenolysis
reduced gluconeogeneis
increased glcyoneogeneis
Inhibition of ketogenesis

Answer 21

reduced ptoelysis

Increased GLUT4 activity - increase glucose uptake

Answer 27

reduced wt gain if insulin given with metformin

Question 28

Problems with actrarapid in the basal-bolus regime

Answer 28

1. absorbed over 3-4hrs: not physiological
2. Must give 15 mins before meal
3. Can - late post prandial hypoglycaemia
4. Immediate post-prandial hyperglycaemia may increase risk of DM complications

Question 29

Short acting insulin analogues

Answer 29

Fast onset and shorted duration
Can be given just before start of meal
Less chance of post-prandial hypoglycaemia
