.The phosphorylation of glucose at position 6 by hexokinase,
2.the conversion of glucose-6-phosphate to fructose-6-phosphate by phosphohexose isomerase,
3.the phosphorylation of fructose-6-phosphate to the 1,6-bisphosphate by phosphofructokinase,
4.the cleavage of fructose-1,6-bisphosphate by aldolase. This yields two different products, dihydroxyacetone phosphate and glyceraldehyde-3-phosphate,12
5.the isomerization of dihydroxyacetone phosphate to a second molecule of glyceraldehyde-3-phosphate by triose phosphate isomerase,
6.the dehydrogenation and concomitant phosphorylation of glyceraldehyde-3-phosphate to 1,3-bis-phosphoglycerate by glyceraldehyde-3-phosphate dehydrogenase,
7.the transfer of the 1-phosphate group from 1,3-bis-phosphoglycerate to ADP by phosphoglycerate kinase, which yields ATP and 3-phosphoglycerate,
8.the isomerization of 3-phosphoglycerate to 2-phosphoglycerate by phosphoglycerate mutase,
9.the dehydration of 2-phosphoglycerate to phosphoenolpyruvate by enolase, and finally
10.the transfer of the phosphate group from phosphoenolpyruvate to ADP by pyruvate kinase, to yield a second molecule of ATP.
