In glycolysis, the first committed step is catalysed by: (A) 2, 3 DPG, (B) Glucokinase, (C) Hexokinase, (D) Phosphofructokinase
Answer is D. Phosphofructokinase catalyzes the committed step of glycolysis, meaning that once fructose 1, 6 - bisphosphate is formed it must go for the glycolytic pathway only.
