22. In an active state of a G protein,
a. the alpha subunit binds to a target protein and the
beta-gamma subunit remains bound to the receptor.
b. the alpha and beta-gamma subunits both can bind to target
proteins.
c. the alpha-beta and gamma subunits both can bind to target
proteins.
d. the gamma subunit can bind to a target protein and the
alpha-beta subunit remains bound to the receptor.

Answer:

The correct option is B  

Explanation:

The alpha and beta-gamma subunits both can bind to target  proteins. Once a G protein becomes active, its alpha subunit and beta-gamma dimer both have the ability to pass on messages in the cell via connecting or binding with other membrane proteins that are involved in the transduction of signals. In this light, B is the best option.
