What is done to glucose, after transport into skeletal muscle, to dedicate it to glycogen synthesis or glycolysis?

Glycogen synthesis:

 

Glycolysis:

Expert Solution
Step 1

In animals the glucose is stored in the form of glycogen that is stored in the muscles and liver of humans.

  • Glycogen is formed out of glucose by the process of glycogenesis.

Glycogen synthesis-

  • In glycogen synthesis the glucose is converted into glucose-6-phosphate.
  • The first step in glycogen synthesis is formation of UDP glucose by UDP glucose pyrophosphorylase.
  • In glycogen synthesis glucose enters into the cell by the help of transporters, the phosphorylation of glucose to glucose 6-phosphate, the isomerization to glucose 1-phosphate and that of formation of uridine 5ʹ-diphosphate the glucose is the direct glucose donor in glycogen synthesis.
  • The glycogen polymer begins with the attachment of glucose to the protein glycogenin.
  • The UDP glucose is the substrate for polymerization in (α1–4) linkages that is catalyzed by glycogen synthase.
