Before a g protein can activate adenylate cyclase, is dissociates into two parts. Thus option C is correct.
<h3>What do you mean by G protein ?</h3>
G proteins refers to guanine nucleotide-binding proteins which belongs to GTPase family.
These proteins help in transmitting signals from a variety of stimuli.
The activity can be controlled by binding and hydrolysis of guanosine triphosphate (GTP) to guanosine diphosphate (GDP).
There are different types of G proteins such as monomeric small GTPases and heterotrimeric G protein complexes
Heterotrimeric G proteins present in a cell activated by G protein-coupled receptors (GPCRs); they both work together to transmit signals, hormones, neurotransmitters etc.
Thus option C is correct.
