Answer:
conversion of glycogen to glucose.
Step-by-step explanation:
In the case of low blood glucose concentration, the body releases the hormone glucagon. Glucagon signals the liver to break down glycogen, a form of stored glucose, into glucose. This glucose is then released into the bloodstream, raising blood glucose levels back to normal.
The other options are not correct because they do not involve the release of glucagon or the breakdown of glycogen.
- Conversion of glucose to glycogen is the opposite of what happens in the case of low blood glucose concentration.
- Working out can help to raise blood glucose levels, but it is not a negative feedback mechanism.
- Resting can help to conserve glucose, but it is not a negative feedback mechanism.
Therefore, the correct answer is conversion of glycogen to glucose.
