<prompt> Insulin secretion is inhibited by all, EXCEPT:SomatostainB-adrenergic blockers propanololB-ketoacidsDiazoxide  <response>: B-ketoacids is a stimulator of insulin secretion not an inhibitor. Factors affecting insulin secretion: Stimulators Inhibitors Glucose Somatostatin Mannose 2-deoxyribose Amino acids leucine, arginine, others Mannoheptulose Intestinal hormones GIP, GLP-1 , gastrin, secretin, CCK, others ? Alpha- adrenergic stimulators nor-epinephrine, epinephrine Beta-keto acids Beta-adrenergic blockers propanolol Acetylcholine Thiazide diuretics Glucagons Galanin Cyclic AMP and various cAMP-generating substance Diazoxide Beta-adrenergic stimulators K depletion Theophylline Phenytoin; Microtubule inhibitors Sulphonylureas Alloxan ; Insulin Ref: Ganong 23e, page 326
