The phosphate group that's released is attached to the glucose molecule at carbon 6. Glucose 6 phosphate is changed to fructose 6-phosphate. More ATP is hydrolysed. The phosphate group that's released is attached to the fructose 6-phosphate at carbon 1. Hexose sugar is activated, > fructose 1,6-bisphosphate. Energy from the hydrolysed ATP molecules activates the hexose sugar. This stage used 2 molecules of ATP for each glucose molecule. 1 of 4 Splitting of hexose 1,6-bisphosphate Each molecule is split into 2 molecules of triose phosphate (3-carbon sugar molecules each with one phosphate group attached.) 2 of 4 Oxidation of triose phosphate 2 hydrogen atoms are removed from each triose phosphate molecule. NAD combines with the hydrogen atoms to form rNAD. 2 molecules of NAD are reduced per glucose molecule. 2 molecules of ATP are formed. 3 of 4 Conversion of triose phosphate to pyruvate 4 enzyme-catalysed reactions convert each triose phosphate molecule to a molecule of pyruvate. Pyruvate is a 3-carbon compound. 2 molecules of ADP are phosphorylated to 2 molecules of ATP. 4 of 4
