3 True/False Questions

1. leukotrines → platelets, endothelial cells, kidney, stomach lining... --> thromboxane synthesis, platelet aggregation and gastric acid secretion

   True        False

2. PAF → major role in inflammation (platelet aggregation, edema, hypotension, psoriasis, asthma shock)

   True        False

3. omega-3 FAs → inhibit synthesis of lipogenic enzymes such as FA synthase and HMG-Coa reductase, promote synthesis of enzymes that break down fats, such as acyl coa DH and carnitine palmitoyltransferase I

   True        False
