The correct answer will be option - Increase in cAMP

Explanation:

Epinephrine is the hormone which is secreted during the stress conditions which prepares the body for fight or flight response. The epinephrine for flight activates the cAMP pathway in the muscles which leads to the activation of glycogenolysis process.

The epinephrine hormone binds the receptors in the muscles which convert ATP to cAMP. The cAMP bind to inactive PKA and activate it. The activated PKA converts the Phosphorylase b which activate the glycogen phosphorylase a which converts the glycogen to glucose 6 phosphate.

Thus, option - Increase in cAMP is the correct answer.
