BIOXI22: CHEMICAL COORDINATION AND INTEGRATION

340947 Which one of the following is a second messenger in hormone action?

1 Calcium
2 \(\mathrm{IP}_{3}\)
3 cAMP
4 All are correct
BIOXI22: CHEMICAL COORDINATION AND INTEGRATION

340948 Statement A :
Membrane-bound receptors normally do not enter the target cell, but generate secondary messengerlikecAMP,IP3, \(\mathrm{Ca}^{++}\) which in turn regulate cellular

metabolism.
Statement B :
Intracellular receptors mostly regulate gene expression by the interaction of hormonereceptor complex with the genome.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
BIOXI22: CHEMICAL COORDINATION AND INTEGRATION

340949 Find out the correct statement
(I) Hormones interact with membrane bound receptors that normally do not enter the target cells.
(II) Steroid hormones generate second messengers.
(III) Iodothyronines have membrane bound receptors

1 I is correct only
2 I and II are correct only
3 II and III are correct only
4 I and III are correct only
BIOXI22: CHEMICAL COORDINATION AND INTEGRATION

340950 Statement A :
Thyroid hormones are iodothyronines while epinephrine is amino acid derivatives in nature.
Statement B :
Hormone receptors present inside the target cell in nucleus, are called intracellular receptors.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
