Which of the following scientists won the nobel prize for discovering second messengers?

A
Martin Rodbell

B
Wilbur Sutherland

C
Robert Huxley

D
Alfred G. Gilman

Solution

Second messengers are molecules that relay signals received at receptors on the cell surface to triggerphysiological changes. Noble prize was awarded to Wilbur Sutherlandfor discovery of second messengers.

pituitary thyroid hormone is also called as collip’s hormone. Cortisol is called as glucocorticoid hormone. Aldosterone is called as mineralocorticoid andsomatostatin is called as inhibiting hormone.
Question 4
4 / -1

Which of the following gas is found to work as a second messenger?

A
SO₂

B
NO

C
N₂O

D
NO₂

Solution

Second messengers are molecules that relay signals received at receptors on the cell surface to trigger physiological changes. Nitrogen oxide (NO) acts as second messenger
Question 5
4 / -1

Old people usually exhibit weaker immune power due to degeneration of

A
Pineal gland

B
Parathyroid gland

C
Thymus gland

D
Hypothalamus

Solution

Thymus gland produces a hormone called thymosin which stimulates the T-cells. T-cells help in producing antibodies in the bodies. In older people weaker immune power is due to degeneration of thymus gland.
Question 6
4 / -1

The Prolactin inhibiting neurohormone is :

A
Acetylcholine

B
Dopamine

C
Catecholamine

D
Serotonin

Solution

The Prolactin inhibiting neurohormone is dopamine. Dopamine is a neurotransmitter that helps control the brain’s reward and pleasure centers.
Question 7
4 / -1

Read the following statements :

i. endocrine system corrects the imbalance originally detected by the nervous system.
ii. nerve cells and endocrine cells exist side by side in adrenal gland and pituitary.

A
both are wrong

B
Statement i) is wrong and ii) is correct.

C
both are correct

D
Statement i) is correct and ii) is wrong.

Solution

Endocrine system corrects the imbalance originally detected by the nervous system. Nerve cells and endocrine cells exist side by side in adrenal gland and pituitary gland.
Question 8
4 / -1

Thyroid gland do not secrete

A
T₄

B
Melatonin

C
Calcitonin

D
T₃

Solution

Pineal secretes a hormone called melatonin.
Question 9
4 / -1

Pituitary dwarfs will not show :

A
normal intelligence

B
stunted growth

C
mental retardation

D
inhibited growth of long bones

Solution

Pituitary dwarf hormone will show normal intelligence, stunned growth and inhibited growth of long bones. Pituitary dwarfs will no show mental retardation.
Question 10
4 / -1

Glucose will be lost in the urine of patients suffering from :

A
diabetes mellitus

B
low blood pressure

C
diabetes insipidus

D
both A & B

Solution

Glucose will be lost in the urine of patients suffering from diabetes mellitus. It a chronic lifelong condition that affects our body abilityto use the energy found in blood.
Question 11
4 / -1

The hormone causing release of milk after the birth of young one is :

A
Oxytocin

B
relaxin

C
progesterone

D
Prolactin

Solution

A hormone called Prolactin secreted by the pituitary gland in the brain is responsible for the alveoli making milk. Prolactin rises when the baby suckles. There is another hormone called Oxytocin that causes tiny muscles around the alveoli to squeeze the milk via small tubes called milk ducts.
Question 12
4 / -1

Read the following statements about gestational diabetes :

i. It must be controlled to protect baby’s growth and development.
ii. It puts women at risk for developing Type – 1 diabetes.

A
both are wrong.

B
both are correct.

C
Statement ii) is wrong and i) is correct.

D
Statement ii) is correct and i) is wrong.

Solution

Gestational diabetes develops during pregnancy. It must be controlled to protect baby’s growth and development. This kind of diabetes never leads to develop type-1 diabetes.
Question 13
4 / -1

The correct matched pair out of the following is :

A
PTH →→ hypocalcemic

B
TSH →→ neurohormone

C
Type 2 diabetes →→ insulin dependent diabetes

D
Glucagon →→ hyperglycemic

Solution

Glucagon hormone released from pancreas increase the sugar level in blood in case deficiency in of glucose. Parathyroid hormone is not hypocalcemin and TSH is not a neurohormone.
Question 14
4 / -1

Thermostat for the body is :

A
pituitary

B
hypothalamus

C
pineal

adrenal

Solution

The body keeps its core temperature constant at about 37 degree Celsius by physiological adjustment controlled by hypothalamus, so called thermostat center.

A
formation of new ovarian follicles.

B
release of secondary oocyte from ovary.

C
implantation of fertilized egg in the uterus.

A
only ii) and iii)

B
only ii) and iv)

C
only i) and ii)

D
only i) and iii)

Solution

Parathyroid hormone is released from parathyroid glands that regulate calcium ions in the body. The person suffering from tumor of parathyroid show symptoms of osteoporosis anddeposition of calcium in kidney tubules.
Question 17
4 / -1

Hormone which acts on hypothalamus to decrease food intake, stimulate satiety and increase energy output is :

A
Leptin

B
Secretin

C
Growth hormone

D
Gastrin

Leptin hormone acts on hypothalamus to decrease food intake, stimulate satiety and increase energy output.Leptin hormone is made by adipose cells.
Question 18
4 / -1

To exert their effect on the target cell, water soluble hormones will need to bind with

A
plasma proteins.

B
cell membrane bound receptors.

C
cytosolic receptors.

D
nuclear receptors.

Solution

Hormones are released in trace amount from endocrine glands and to exert theireffect on the target cell, water soluble hormones will need to bind with cell membrane boundreceptors.
Question 19
4 / -1

Some girls develop male secondary sexual characters like beard, moustaches, hoarse voice etc. This is called

A
gonadotropin excessism

B
adrenal virilism

C
eunuchoidism

D
cushions syndrome

Solution

Development of secondary sexual characters like beard, moustaches , hoarse voice etc in girls is called adrenal virilism. This occurs due to excessive secretion of adrenaline hormone.

C
a)-iv, b)-iii, c)-ii, d)-i

D
a)-iv, b)-iii, c)-i, d)-ii

Solution

Follicle stimulating hormone acts on sertoli cells. Luteinsing hormone acts on interstitial cells. Cortisol cells acts on liver and Aldosterone hormone acts on kidney tubule.
