Question

The enzyme which converts glucose to glucose 6-phosphate is

• A. Phosphorylase
• B. Glucose-6-phosphatase
• C. Hexokinase
• D. Glucose synthetase

Answer 1

The correct option is C Hexokinase

During the process of Glycolysis, an organic substrate like glucose is reduced to pyruvic acid with the production of ATP and NADH${}_2$. The first step of Glycolysis involves phosphorylation of glucose to glucose-6-phosphate. The enzyme hexokinase phosphorylates glucose with a phosphate from ATP along with Mg2+ as a cofactor.

So the correct answer is 'Hexokinase'.
