Question

Phosphorylation of glucose during glycolysis is catalysed by

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

Answer 1

Answer: (C)

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