So insulin is inhibited by low glucose concentrations, which is the opposite of glucagon. So we see when glucagon is inhibited, our insulin is activated. And when our glucagon is activated, the insulin is inhibited. 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.
