Sample questions

1. 1.Insulin lowers blood glucose mainly by acting on hepatocytes and adipocytes to:
   • A.Enhance cellular glucose uptake and utilisation
   • B.Stimulate glycogenolysis in the liver
   • C.Stimulate gluconeogenesis
   • D.Reduce cellular glucose uptake
2. 2.Assertion (A): Endocrine glands are called ductless glands. Reason (R): The secretions of endocrine glands, called hormones, are released directly into the blood rather than through ducts.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
3. 3.Assertion (A): Steroid hormones and iodothyronines mostly regulate gene expression. Reason (R): These hormones interact with intracellular receptors and their hormone-receptor complex interacts with the genome.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true

   • A.Releases its secretion into the blood as it lacks ducts
   • B.Releases its secretion through a duct onto an epithelial surface
   • C.Secretes only digestive enzymes
   • D.Secretes nutrient chemicals in large amounts
5. 5.Which cells of the testis produce androgens, mainly testosterone?
   • A.Leydig (interstitial) cells
   • B.Sertoli cells
   • C.Follicular cells
   • D.Corpus luteum cells
