The major product from the action of glycogen phosphorylase and the debranching enzyme glucantransferase is 1) fructose-6-phosphate 2) udp-glucose 3) glucose-1-phosphate 4) glucose-6-phosphate

Glucose-1-phosphate

Explanation:

Glycogen is the major storage component in animals, that stores the excess glucose for future use.When glucose levels go down below normal levels, the hormone glucagon is produced to trigger the liver cells to break down glycogen to glucose that is then released to restore normal blood sugars.The break down of glycogen to glucose is known as glycogenolysis that is catalyzed by the enzymes glycogen phosphorylase and the debranching enzyme glucantransferase.Debrancing enzyme breaks down the glycogen branches while the glycogen phosphorylase breaks down shorter chains of glycogen to glucose-1-phosphate.Consequently, glucose-1-phosphate is converted to glucose-6-phosphate and then to glucose.
