Verified
When a hormone binds to a membrane-bound receptor and activates G proteins,
A) ion channels could be opened.
B) IP3 may be activated.
C) cyclic AMP production may be increased.
D) DAG may be activated.
E) All of the choices are correct.
Membrane-bound Receptor
A type of cell receptor that is anchored in the cell membrane and interacts with extracellular molecules to trigger signals within the cell.
G Proteins
Guanine nucleotide-binding proteins that act as molecular switches inside cells, involved in transmitting signals from a variety of stimuli outside a cell to its interior.
Cyclic AMP
A secondary messenger important in many biological processes, such as the regulation of metabolism.

Final Answer :
E
Explanation :
When a hormone binds to a membrane-bound receptor and activates G proteins, it can lead to various cellular responses including the opening of ion channels, activation of enzymes like adenylyl cyclase (which increases cyclic AMP production), and activation of phospholipase C (which leads to the production of diacylglycerol (DAG) and inositol triphosphate (IP3)). Therefore, all of the choices are correct.
