Mix Examples-Chemical Coordination and Integration Questions in English

(A) The correct matching is as follows:
$A$. Catecholamines (e.g.,adrenaline and noradrenaline) are secreted by the adrenal medulla and are known as stress hormones,which help the body respond to emergency situations. Thus,$A-(iv)$.
$B$. $MSH$ (Melanocyte Stimulating Hormone) acts on melanocytes to regulate skin pigmentation. Thus,$B-(iii)$.
$C$. Thymosins are secreted by the thymus gland and play a major role in the differentiation of $T$-lymphocytes,which provide cell-mediated immunity. Thus,$C-(ii)$.
$D$. Melatonin is secreted by the pineal gland and plays a very important role in the regulation of a $24$-hour (diurnal) rhythm of our body,such as the sleep-wake cycle and body temperature. Thus,$D-(i)$.
Therefore,the correct sequence is $A-(iv), B-(iii), C-(ii), D-(i)$.

(A) $A-q, B-p, C-t, D-r$
$1$. $FSH$ (Follicle-Stimulating Hormone) stimulates the development of ovarian follicles and is involved in the process of ovulation.
$2$. $GH$ (Growth Hormone) is responsible for the normal growth and development of the body.
$3$. Prolactin is a hormone that stimulates the mammary glands to produce milk (milk secretion).
$4$. Oxytocin acts on the smooth muscles of the uterus and stimulates their contraction during childbirth, a process known as parturition.

(A) The correct matches are as follows:
$A$. Cortisol: It is a glucocorticoid that produces anti-inflammatory reactions and suppresses the immune response $(II)$.
$B$. Aldosterone: It is a mineralocorticoid that acts mainly at the renal tubules and stimulates the reabsorption of $Na^+$ and water and excretion of $K^+$ and phosphate ions $(III)$.
$C$. Cholecystokinin $(CCK)$: It acts on both the pancreas and the gallbladder and stimulates the secretion of pancreatic enzymes and bile juice $(IV)$.
$D$. Progesterone: It supports pregnancy and also stimulates the formation of alveoli (sac-like structures which store milk) in mammary glands $(I)$.
Therefore,the correct matching is $A-II, B-III, C-IV, D-I$.
