Muscle cells are not able to supply glucose for other tissues because they do not contain which enzymes?

Muscle cells are not able to supply glucose for other tissues because they do not contain Protein Phosphatase enzymes  

Explanation:

Protein phosphatases are a called mammalian class regulatory enzyme that catalyse the “dephosphorylation of phosphoserine” and phosphothreonine residues in proteins. Some Specific processes are controlled by protein phosphatases. It includes glycogen metabolism, mitosis, muscle contraction and also transduction of hormonal signals.

Now it become proved that protein phosphatases are equal value as protein kinases in controlling a wide level of variety of metabolic processes through dephosphorylation-induced conformational changes with concomitant decreasing or increasing in the activity of key enzymes.
