A. | Epinephrine is a peptide hormone. |
B. | Progesterone is a peptide hormone. |
C. | Hormones that interact with membrane bound receptors normally do not enter the target cell, but generate second messengers. |
D. | Hormones that interact with intracellular receptors mostly regulate gene expression. |
E. | Insulin is an amino acid derivative hormone. |
Assertion (A): | FSH which interacts with membrane bound receptors does not enter the target cell. |
Reason (R): | Binding of FSH to its receptors generates second messenger (cyclic AMP) for its biochemical and physiological responses. |
1. | Both (A) and (R) are correct and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are correct but (R) is not the correct explanation of (A). |

How does steroid hormone influence the cellular activities?
1. | Using aquaporin channels as second messenger |
2. | Changing the permeability of the cell membrane |
3. | Binding the DNA and forming a gene-hormone complex |
4. | Activating cyclic AMP located on the cell membrane |
Identify A, B and C in the diagrammatic representation of the mechanism of hormone action.
Select the correct option from the following:
