Answer:

The correct answer is - D. The initiation of a signaling mechanism that leads to the breakdown of glycogen into glucose that can then serve as the fuel for ATP production.

Explanation:

In challenging or dangerous conditions, the body releases a hormone called Epinephering which is a fight or flight hormone that provides a high amount of energy for the particular action.

Epinephrine hormone binds to beta-adrenergic receptors present on muscles and responsible for the rapid conversion of glycogen to glucose-1-phosphate. The glucose results in condition to rapid synthesis of ATP in muscles and thus helps in muscle actions.
