The magnification of the signal from a water-soluble hormone is achieved through an increase in . water-soluble hormone in the bloodb. adenylate cyclase in the plasma membranec. plasma membrane receptorsd. phosphodiesterase in the cytoplasme. camp in the cytoplasm

cAMP in the cytoplasm

Explanation:

Water-solubile hormons cannot pass through the cell membrane, so they bind to their transmembrane receptors. As a result of their binding, receptor changes its shape (conformational change) and a signal cascade in the cytoplasm begins. Signal cascade includes the activation of primary and secondary messengers. Camp is a molecule often generated as a second messenger with the roleto amplify the signal in response to hormone binding.
