epi has action on alpha 1 and 2 and beta 1 and 2. so the alpha 2 activity decreases insulin release and the beta 2 causes increase in glugacon which inhibits insulin as well.
norepi acts on alpha 1 and 2 and beta 1 only.. so it decreases insulin release only by acting on alpha 2. hope that makes sense..

Correct me if I am wrong......
......but I thought insulin inhibits glucogan but Glucogon has no effect on insulin release.

insulin inhibits glucagon but glucagon stimulates insulin release?is this right?

Yes hemostat,
Glucogon is a peptide hormone, with AA sequence similar to secretin hence stimulates insulin release. (Source Kaplan Lecture notes).
