Endosomal Fractions Can Be Isolated from Cells Using Differential Centrifugation $\beta$

Essay

Endosomal fractions can be isolated from cells using differential centrifugation. Using this technique, would you expect to find more or fewer $\beta$ -adrenergic receptors in the purified
endosomes in a wild-type liver cell that had been stimulated with glucagon OR in a mutant liver cells that lacks $\beta$ -adrenergic receptor kinase that had been stimulated with glucagon? In explaining your answer describe the role of $\beta$ -adrenergic receptor kinase.
