Hormone are called chemical signals that stimulate specific target tissues . Their specific is due to the presence of signal receiving 'receptors' only in the respective target tissues. Where are these receptors present in case of hormones of protein nature

A

Extra cellular matrix

B

Blood

C

Plasma membrane

D

Nucleus

Text Solution

Verified by Experts

The correct Answer is:
C
Hormones are called chemical signals that stimulate specific target tissues. Their specificity is due to the presence of signal receiving 'receptors' only in the respective target tissues. In case of hormones of protein nature receptors present on plasma membrane.

Hormones are called chemical signals that stimulate specific target tissues. Which is the corret location of these receptors in case of protein hormones?

Read the given paragraph and select the option that correctly fills the blanks in it. Hormones produce their effect on target tissue by binding to specific A called hormone receptors located in the target tissues only water soluble hormones usually need B receptor that generate C messenger for regulating through cell membrane and bind to E receptors, mostly nuclear receptors. The hormone receptor complex enter the nucleus and moslty regulate gene expression or chromosome function by interaction of hormone receptor complex with the genone.

    Over production of acid in the stomach causes irritation and pain. In severe cases, ulcers are developed in the stomach. Until 1970, only treatment for acidity was administration of antacids, such as sodium hydrogencarbonate or a mixture of aluminium and magnesium hydroxide. However, excessive hydrogencarbonate can make the stomach alkaline and trigger the production of even more acid. Metal hydroxides are better alternatives because of being insoluble, these do not increase the pH above neutrality. These treatments control only symptoms, and not the cause. Therefore, with these metal salts, the patients cannot be treated easily. In advanced stages, ulcers become life threatening and its only treatment is removal of the affected part of the stomach. A major breakthrough in the treatment of hyperacidity came through the discovery according to which a chemical, histamine stimulates the secretion of pepsin and hydrochloric acid in the stomach. The drug cimetidine (Tegamet), was designed to prevent the interaction of histamine with the receptors present in the stomach wall. This resulted in release of lesser amount of acid. The importance of the drug was so much that it remained the largest selling drug in the world until another drug, ranitidine (Zantac), was discovered. What happens in advanced cases to the patients of hyperacidity ?

    Hormones produce their on target tissue by binding to specific underline(A) called hormone receptors located in the target tissues only . underline(B) soluble hormones usually need underline(C) receptor that generate underline(D) messen-gers for regulating cellular metabolism . underline(E) soluble hormones can pass through cell membrane and bind to underline(F) receptors, mostly underline(G) receptors. The hormone receptor complex enter the underline(H) and mostly regulate gene expression or chromosome function by interaction of hormone -receptor complex with the underline(I)
