Kennedi Mclean · Answer 1

c) They result in production of diffusible second messengers.

Explanation:

In G protein coupled receptors and steroid hormone receptors, when a ligand binds to these receptors, it activates one or more signal transduction systems, which initiate different cascades of events that alter the concentration of intracellular second messengers which stimulates other cascade of reactions.

4. c) They result in production of diffusible second messengers

Explanation:

G-protein coupled receptors (GPCR) and steroid hormone receptors have common in the way that both result in the production of diffusible second messengers into the cytosol for further initiation of signal transduction pathways in the target cell. Hence option (c) is the correct answer.
