Glycolysis the decomposition (lysis) of glucose to pyruvate(or pyruvavic acid).
- At the beginning, 2 ATP is added. The first several steps require the input energy.
- Then, 2 NADH are produced. NADH is a coeznyme, accepting 2 electrons from substrate molecule.
- 4 ATP are produced.
- 2 pyruvate are formed.
In summary, glycolysis takes 1 glucose and turns it into 2 pyruvate, 2 NADH, and a net gain 2 ATP( synthesised 4, but used 2 ATP).
