Which Statement About G Protein Signaling Is False?
A) Hormone $\alpha$

Which statement about G protein signaling is false?

A) Hormone binding induces an interaction of the receptor with the G protein, stimulating the release of GDP and the exchange of GTP on the $\alpha$ subunit.
B) Once activated, the GTP-bound $\alpha$ subunit dissociates from $\beta$$\gamma$ and interacts with its target.
C) Activity of the $\alpha$ subunit is terminated by the hydrolysis of GTP to GDP.
D) The $\alpha$ subunit becomes deactivated when the hormone dissociates from the receptor.
