With regard to hormones, identify the correct statements.
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.
Choose the most appropriate answer from the options given below:
1. A and B only
2. C and E only
3. C and D only
4. B and C only

Please attempt this question first.

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
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.
In the light of the above statements, choose the most appropriate answer from the options given below:
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).
3. (A) is correct but (R) is not correct.
4. (A) is not correct but (R) is correct.

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
