What role does the GTPase activity of G proteins play within signaling pathways?

Question

What role does the GTPase activity of G proteins play within signaling pathways? It produces cGMP, a second messenger. It terminates the signal of the G protein. It increases the signal of the G protein as long as GDP remains bound. It causes permanent inactivation of the G protein.

Explanation / Answer

Answer:- It produces cGMP, a second messenger.

GTPases are hydrolase enzymes that can bind and hydrolyze guanosine triphosphate (GTP).

GTPase activity of G-proteins leads to:

4. hydrolysis of GTP returning the G protein to its original level of activity before activation by the endogeneous lignand.

1. Stimulating the activity of enzymes by producing energy. 2. Production of cGMP as a second messenger. 3. synthesis of GTP as an energy source.

4. hydrolysis of GTP returning the G protein to its original level of activity before activation by the endogeneous lignand.
