Select the correct statement

  1. Glucagon is associated with hypoglycemia.
  2. Glucocorticoids stimulate gluconeogenesis
  3. Insulin acts on pancreatic cells and adipocytes.
  4. Insulin is associated with hyperglycemia.

Answer

(2) Glucocorticoids stimulate gluconeogenesis

Solution

As per NCERT, glucocorticoids (mainly cortisol) of the adrenal cortex stimulate gluconeogenesis, lipolysis and proteolysis ⇒ statement (2) is correct.

(1) Glucagon stimulates glycogenolysis and gluconeogenesis and is a hyperglycaemic hormone, not associated with hypoglycaemia.

(3) Insulin acts mainly on hepatocytes and adipocytes, not on pancreatic cells.

(4) Insulin is a hypoglycaemic hormone; it lowers blood glucose.

Answer: (2)

  1. epiphyseal plates close after adolescence
  2. bones lose their sensitivity to growth hormone in adults
  3. muscle fibres do not grow in size after birth
  4. growth hormone becomes inactive in adults.
