PLEASE ANSWER 6 A and B !!! THANK YOU!

6. Individuals lacking liver glucose-6-phosphatase accumulate a large amount of glycogen in the liver, while their blood glucose levels are only slightly increased when administered high doses of glucagon (glucagon activates glycogen degradation and inhibits glycogen synthesis). a. (1 pt) What chemical reaction does glucose-6-phosphatase catalyze and in which metabolic pathway is this enzyme found? b. (1 pt) What is the metabolic source of the glucose that causes the blood glucose levels to rise slightly? Justify your answer with key metabolic information regarding the source of the glucose
