WebGlycolysis is the metabolic pathway that converts glucose ( C6H12O6) into pyruvate. The free energy released in this process is used to form the high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH). [1] Glycolysis is a sequence of ten reactions catalyzed by enzymes . WebMar 2, 2024 · The pathway of glycolysis can be seen as consisting of two separate phases. The first is the chemical priming phase requiring energy in the form of ATP, and the second is considered the energy-yielding phase. In the first phase, two equivalents of ATP are used to convert glucose to fructose 1,6-bisphosphate (F1,6BP).
