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.
line A is the answer because enzymes act as catalyst for chemicals reactions which means that they help speed up the production of products from a chemical reaction
