Which enzyme catalyzes the initial committed step in the glycolytic pathway?

Explanation

Hexokinase is responsible for the first committed step in glycolysis, where it phosphorylates glucose to glucose-6-phosphate, committing it to the glycolytic pathway. Phosphofructokinase acts later in the pathway, glucose-6-phosphatase is involved in gluconeogenesis, and enolase functions in a subsequent step of glycolysis.
