Answer #1

The correct option is a

during prolonged fasting , As all the glucose present in the blood is consumed, energy requirement is fulfilled from breaking down of glycogen (stored energy),which releases glucose into the bloodstream . This process is called as glycogenolysis.

in this process glycogen is first converted into to glucose 1 phosphate which further converted into glucose 6 phosphate.

this glucose-6-phosphate enters into liver where by the action of enzyme glucose-6-phosphatase it gives out glucose.
