Before a g protein can activate adenylate cyclase, a) it releases a second messenger. b) it hydrolyzes gtp. c) is dissociates into two parts. d) it phosphorylates the enzyme.

Respuesta :

Before a g protein can activate adenylate cyclase, is dissociates into two parts. Thus option C is correct.

What do you mean by G protein ?

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.
