Gavin Meza · Answer 1

Option B

Explanation:

Water soluble hormones associate with the G protein of cAMP. This G protein is intra-cellular i. e found inside the cell.

However in case of lipid derived hormones, the hormone has to diffuse through the cell across the plasma membrane to bind to DNA or the intra-cellular receptors. This regulates the gene transcription and induces protein production that affects the cell functioning for a long time.

Hence, option B is correct
