If the liver begins to release glycogen because the pancreas releases glucagon, the amount of ______ in the bloodstream must be
zheka24 [161]

If the liver begins to release glycogen because the pancreas releases glucagon, the amount of <u>the concentration of insulin</u> in the bloodstream must be too low.

<u>Explanation:</u>

Glucagon is considered to be the primary catabolic hormone of the body and is produced by the pancreas.

When insulin in the bloodstream falls low, then the pancreas causes the liver to convert stored glycogen into glucose. Insulin allows glucose to be used by insulin-dependent tissue.

The body releases insulin and glucagon to keep the blood glucose level stable in the body. Under stress, the level of glucagon increases in the body.
