What does cause an increase of insulin?

Why doesn't decreased insulin secretion during stress cause problems?

• During fight-or-flight situations, alpha 2 receptors ( which are inhibitory receptors ) of the pancreatic beta cells are stimulated, and as a result there's decreased insulin production. While it benefits the body by producing increased blood sugar level, I don't understand why Insulin doesn't cause some problems. Such as, since insulin increases glucose intake by the muscle tissues ( skeletal muscles are supposed to be used more in flight-or-fight situations ) and increases glycolysis ( which produces energy ), wouldn't decreased insulin release during flight-or-fight situations cause less glucose intake and less glycolysis ( as a result less energy production ) by the muscle tissues? And wouldn't less energy produced by the muscle tissues cause them work less efficiently?

• Answer:

  During stress, the hormones working to catabolize will be released because cells need glucose from the glucose storage. In this condition, no signal given to the beta cell receptors to secrete insulin. In this way, low concentration of insulin should be normal and even when the insulin is lower than it is supposed to be, it doesn't matter at all because no signal is given during the stress.
