A Scientist Is Designing a New Drug That Will Mimic

Multiple Choice

A scientist is designing a new drug that will mimic a particular signal molecule and reduce its activity. It is therefore necessary to produce a molecule that will

A) bind specifically to the receptor molecule, induce a change in shape of the molecule which will ultimately prevent a cellular response.
B) bind specifically to adenylyl cyclase to activate protein kinase A and stimulate the cellular response.
C) bind to the membrane bilayer and cause membrane depolarisation to prevent the response.
D) bind to the membrane receptor and open a ligand-gated channel.
E) bind to phospholipase C and activate the G-protein to prevent a cellular response.
