Web10 mrt. 2024 · Equation of Glycolysis. The following equation well summarizes the process of glycolysis: C6H12O6 + 2ADP + 2Pi + 2NAD+ → 2C3H4O3 + 2H2O + 2ATP + 2NADH + 2H+ C6H12O6 is glucose and C3H4O3 is pyruvate. ADP and NAD stand for Adenosine diphosphate and Nicotinamide adenine dinucleotide, respectively. Steps of Glycolysis. … WebSeveral steps in glycolysis are regulated, but the most important control point is the third step of the pathway, which is catalyzed by an enzyme called phosphofructokinase (PFK).
