If a fret experiment was carried out with blue fluorescent protein attached to the î± subunit of a stimulatory g-protein and a green fluorescent protein attached to the ãÿ subunit, the presence of a strong fret signal would be associated with:
a) interaction of a g protein-coupled receptor with an antagonist.
b) hydrolysis of gtp in the î± subunit.
c) increased concentrations of camp.
d) both interaction of a g protein-coupled receptor with an antagonist and hydrolysis of gtp in the î± subunit.
e) both hydrolysis of gtp in the î± subunit and increased concentrations of camp
