Answer :
Answer:
The answer is that the two receptors work as binders , thereby, they activate the same Ga subunit, Gsa, and this indirectly to the activation of PKA.
Explanation:
Note that, the action that occurred within the cell depends on heterotrimetric G protein that was activated by the receptor. In specificity, the receptors for glucagon and epinephrine interact with the intracellular Gsa subunit of a heterometric protein. Activation of Gsa leads to the same downstream which signal events, hence the same cellular responses despite the difference between the ligand-receptor interaction.
