Question
Phosphorylation of glucose during glycolysis is catalyzed by which of the following?
- Phosphoglucomutase
- Phosphoglucoisomerase
- Hexokinase
- Phosphorylase
Hint:
Phosphorylation is the process of enzymatic addition of a phosphate group from ATP to a compound.
The correct answer is: Hexokinase
Phosphorylation of glucose during glycolysis is catalyzed by Hexokinase.
- Phosphorylation refers to the process in which phosphate group from ATP is donated to the hexose sugar.
- In the first step of glycolysis, glucose, a stable 6C sugar is phosphorylated to of glucose-6-phosphate during glycolysis, which is catalyzed by the help of the enzyme hexokinase.
- Here, a phosphate group is donated to the sixth carbon atom of the glucose.
