Following its initial activation,what becomes of a G protein?
A)The G-protein a subunit containing a GTP eventually reassociates with the G-protein bg dimer.
B)The G-protein a subunit GTP is hydrolyzed to GDP allowing reassociation of the G-protein a subunit and bg dimer.
C)The G-protein a subunit is digested and recycled.
D)It spontaneously loses activity within a few seconds.
E)The receptor becomes internalized.

After initial activation, the G-protein a subunit containing GTP is eventually hydrolyzed to GDP, allowing for reassociation with the G-protein bg dimer. This process helps to terminate the signal transduction pathway activated by the G protein.
