Glucagon stimulates the release of glucose from the liver through a pathway that involves the activation of adenyl cyclase. Without adenyl cyclase activity, this pathway would be blocked, and glucagon would no longer be able to stimulate the release of glucose from the liver. Insulin, cortisol, thyroxine, and leptin do not stimulate the release of glucose from the liver via the adenyl cyclase pathway, so their effects would not be affected by the absence of adenyl cyclase activity.
