Explanation Explanation/justification for the correct answer: Option (e) all of these are correct. Activated G protein can result in the opening or closing of ion channels, activation of adenylate cyclase, alter the activity of inositol triphosphate or inhibit the synthesis of cAMP by shutting down the cAMP pathway. So, the correct answer is option (e). Explanation for incorrect answer: Option (a) cause ion channels to open or close. By activating the G proteins, the ion channels can open or close to alter the permeability of the membrane for specific ions, but that is not the only characteristic of activated G protein. So, this is an incorrect option. Option (b) activate adenylate cyclase...
