Why does insulin promote protein and fat synthesis?
1. Inhibition of glycogen synthesis (liver glycogen 5-6%)
2. Activation of acetyl-CoA carboxylase, leading to an excess of citrate & isocitrate ions and conversion of acetyl-CoA to Malonyl-CoA
3. Activation of lipoprotein lipase which splits triglycerides into fatty acids, which are transported into adipose cells and stored.
