Answer:

Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.

Step-by-step explanation:

  • Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
  • Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
  • In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP

Result: Glucokinase and hexokinase are used in the first step of glycolysis.
