Match the following hormones with the respective disease : Select the correct option.

  1. (a)-(v), (b)-(iv), (c)-(i), (d)-(iii)
  2. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
  3. (a)-(v), (b)-(i), (c)-(ii), (d)-(iii)
  4. (a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)

Answer

(1) (a)-(v), (b)-(iv), (c)-(i), (d)-(iii)

Solution

As per NCERT:

(a) Insulin deficiency causes prolonged hyperglycaemia, i.e., diabetes mellitus ⇒ (v)

(b) Deficiency of iodine (thyroxin synthesis) enlarges the thyroid gland, i.e., goitre ⇒ (iv)

(c) Underproduction of hormones (corticoids) by the adrenal cortex causes Addison's disease ⇒ (i)

(d) Excess growth hormone in adults (middle age) causes acromegaly ⇒ (iii)

∴ (a)-(v), (b)-(iv), (c)-(i), (d)-(iii)

Answer: (1)

  2. Using aquaporin channels as second messenger
  3. Changing the permeability of the cell membrane
  4. Binding to DNA and forming a gene-hormone complex
Ques. 3NEET (UG) 2019

Which of the following glucose transporters is insulin-dependent?

  1. GLUT III
  2. GLUT IV
  3. GLUT I

Ques. 4NEET 2018

Which of the following is an amino acid derived hormone?

  1. Ecdysone
  2. Estriol
  3. Epinephrine
  4. Estradiol
Ques. 5NEET 2017

GnRH, a hypothalamic hormone, needed in reproduction, acts on

  1. anterior pituitary gland and stimulates secretion of LH and FSH
  2. posterior pituitary gland and stimulates secretion of oxytocin and FSH
  3. posterior pituitary gland and stimulates secretion of LH and relaxin
  4. anterior pituitary gland and stimulates secretion of LH and oxytocin.
Ques. 6NEET 2017

Hypersecretion of growth hormone in adults does not cause further increase in height, because

  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.
Ques. 7NEET 2016 (Phase 1)

Which of the following pairs of hormones are not antagonistic (having opposite effects) to each other?

  1. Aldosterone – Atrial Natriuretic Factor
  2. Relaxin – Inhibin
  3. Parathormone – Calcitonin
  4. Insulin – Glucagon
Ques. 8NEET 2016 (Phase 1)

The amino acid tryptophan is the precursor for the synthesis of

  1. estrogen and progesterone
  2. cortisol and cortisone
  3. melatonin and serotonin
  4. thyroxine and triiodothyronine.
Ques. 9NEET 2016 (Phase 2)

Graves' disease is caused due to

  1. hyposecretion of thyroid gland
  2. hypersecretion of thyroid gland
  3. hyposecretion of adrenal gland
  4. hypersecretion of adrenal gland.
Ques. 10NEET 2016 (Phase 2)

Name a peptide hormone which acts mainly on hepatocytes, adipocytes and enhances cellular glucose uptake and utilisation.

  1. Insulin
  2. Glucagon
  3. Secretin
  4. Gastrin
Ques. 11NEET 2016 (Phase 2)

The posterior pituitary gland is not a 'true' endocrine gland because

  1. it is provided with a duct
  2. it only stores and releases hormones
  3. it is under the regulation of hypothalamus
  4. it secretes enzymes.
