Which enzyme helps in transfer of phosphate group from ATP to a carbohydrate?

  • A
    Phosphatase
  • B
    ATPase
  • Correct answer
    C
    Phosphorylase
  • D
    Catalase

Solution

Transfer of phosphate group from ATP to a carbohydrate is referred to as phosphorylation and is carried out in the presence of phosphorylase enzymes. E.g., glucose (a carbohydrate) is phosphorylated to glucose-6-phosphate by ATP in the presence of enzyme hexokinase or glucokinase and $\mathrm{Mg}^{2+}$.

Hence, the correct answer is option: 'C'.
