process of glycolysis

HideShow resource information



  •  one ATP is hydrolysed and the phosphate group attaches to glucose at carbon 6.
  • Glucose 6-phosphate is changed to fructose 6-phosphate.
  • Another ATP is hydrolysedand the phosphate group attaches to fructose 6-phosphate at carbon 1.
  • The energy from ATP activates the hexose sugar, it is known as hexose 1,6  bisphosphate.

Splitting of hexose 1,6 bisphosphate:

  • Hexose 1,6 bisphosphate is split into 2 molecules of triose phosphate
1 of 2

Oxidation of Triose Phosphate:

  • two hydrogen atoms are removed from each triose phosphate molecule (involves dehydrogenase enzymes)
  • NAD combines with the hydrogen to become reduced NAD
  • two molecules of ATP are formed (substrate-level phosphorylation)

Conversion of Triose Phosphate to Pyruvate

  • Triose phosphate is converted to an intermediate compound, then to pyruvate.
  • two molecules of ATP are formed (substrate level phosphorylation)


net gain of 2ATP (total 4 ATP) , 2 reduced NAD, 2 pyruvate.
