Question

Phosphorylation of glucose during glycolysis is catalysed by

• A. phosphoglucomutase
• B. phosphoglucoisomerase
• C. hexokinase
• D. phosphorylase

Answer 1

Answer: (C)

hexokinase

Answer 2

During glycolysis, glucose is phosphorylated to glucose-$6$-phosphate by $ATP$ in the presence of enzyme hexokinase or glucokinase and $Mg^{2+}$ as follows : Glucose ${+ ATP ->[\text{Hexokinase}][Mg^{2+}] }$ Glucose-$6$-phosphate $+ ADP$
