Now, insulin can also be inhibited by other hormones, just like glucagon can, for example. Norepinephrine, the hormone that is released by our adrenal gland, can also inhibit our insulin hormone. So let's take a look at the following diagram that basically describes the connection between glucagon and insulin. So let's suppose we are fasting for a long time. And because we are fasting, that means the glucose concentration inside our blood is low. So let's suppose we are experiencing high pole glycemia.
