Which of these statements is true regarding receptors for peptide or amine hormones?
a. If bound to the hormones themselves, receptors for peptide or amine hormones can act as transcription factors.
b. Receptors for peptide or amine hormones are typically located in the plasma membrane of cells.
c. Receptors for peptide or amine hormones are typically located in the cytoplasm of cells.
d. Peptide and amine hormones do not require receptors, as these hormones can diffuse directly across the plasma membrane of a cell.

Answer :

answer:

B

Explanation:

1. Receptors for peptide or amine hormones located on the plasma membrane of cells, whereas receptors for lipid-soluble hormones are usually found within or inside  the cytoplasm because lipid-soluble hormones can easily cross the cytoplasm.

2. After binding hormone,  there is the change in the receptor and the receptor can initiate multiple signaling pathways.

3. These pathways finally causes the changes in the behavior of the target cells.

4. There are various type of hormones, some of them are excitatory and some are inhibitory.
