Question

Which glycolytic enzyme uses ATP to phosphorylate glucose?

A) alcohol dehydrogenase
B) phosphoglucoisomerase
C) aldolase
D) hexokinase
E) pyruvate kinase

Answer 1

Hexokinase is the glycolytic enzyme that uses ATP to phosphorylate glucose.

Step-by-step explanation:

The enzyme responsible for phosphorylating glucose during glycolysis is hexokinase. Hexokinase adds a phosphate group to glucose, converting it into glucose-6-phosphate. This step requires one ATP molecule to provide the phosphate group.
