In glycolysis, ATP is synthesised:
1. during conversion of 1,3 biphosphoglyceric acid to 3-phosphoglyceric acid and during conversion of phosphoenolpuruvate to pyruvic acid
2. during conversion of glucose to glucose-6-phospate and during conversion of fructose-6-phosphate to fructose – 1,6- biphosphate
3. during conversion of glucose to glucose-6-phospate and during conversion of glucose-6-phosphate to fructose-6- phosphate
