Why is muscle glycogen unable to directly raise blood glucose levels?

Show Answers

Muscle cells do not have glucose 6-phosphataseMuscle lacks the enzyme phosphoglucoisomeraseGlucokinase is missing in muscle tissueGlycogen phosphorylase is absent in muscleMuscle cannot store glycogen

Explanation

Muscle glycogen cannot directly increase blood glucose because muscle cells lack glucose 6-phosphatase, the enzyme required to convert glucose-6-phosphate into free glucose that can be released into the bloodstream.
