Answer:It would maintain high cAMP levels and elevate glucose mobilization.
Explanation:
Gas stimulates adenylate cyclase, leading to the generation
of cAMP. This signal then leads to glucose mobilization. If cAMP phosphodiesterase were inhibited, then
cAMP levels would remain high even after the termination of the
epinephrine signal, and glucose mobilization would continue
The medication would be the controlled variable, the factor that remains constant.
