(Phospholipase A2) Phosphatidyl inositol DAG G Protein (LOX) Modified from Fig. 6-16 Eicosanoids (20-C) synthase from arachidonic acid through enzyme Epoxygenase inhibition of COX1 lead to stomach bleeding integrin receptor (membrane-bound receptor) have 2 dissimilar subunit, alpha and beta. when this receptor bind to its ligand (molecules of extracellular matrix or antibodies or blood-clotting proteins). when the receptor binds its ligands, then the receptor clustered and become active...
