The correct answer is:
hexokinase
Hexokinase catalyses the conversion of glucose into glucose-6-phosphate by the use of ATP molecule in the phosphorylation reaction.
Phosphoglucomutase is an enzyme that transfers a phosphate group in D-glucose monomer from 1 to 6 position of carbon in forward direction.
Phosphoglucoisomerase catalyses conversion of glucose6-phosphate to fructose-6-phosphate.
Phosphorylase is an enzyme which catalyses the addition of phosphate $\mathrm{PO}_4{ }^{-}$group from inorganic phosphate to an acceptor.
