Upon getting his annual physical exam, a 55-year-old man is noted to have a body mass index of 33 (above 30 = obese) and high blood pressure

His blood chemistry indicates hyperlipidemia, hypertriglyceridemia, and hypercholesterolemia. Furthermore, his fasting blood glucose level is 120 mg/dL (elevated). His physician suspects type 2 diabetes and orders a glucose tolerance test. The patient drinks 75 g of glucose and then has his blood glucose measured at 2 hr. The 2-hr glucose level is 190 mg/dL (high end of glucose intolerance range; the diagnosis of diabetes is equal to or greater than 200 mg/dL). The most likely reason for this patient's glucose intolerance is: A. autoimmune destruction of the ? cells B. impairment of ATP-sensitive K+ channel C. insulin resistance D. low leptin levels E. impairment of GLUT2 function
