In glycolysis, glucose is converted to pyruvate

your body needs energy before its too late

every step leads towards ATP

2 used up at one and three 

a final product of 4 ATP is no debate

Glucose goes to 6-phosphate through hexokinase

a phosphate group takes hydrogen's place

phosphoglucose isomerase converts it to fructose 6 phosphate at two

the six member molecule goes to five through nothing new

step 3 uses ATP to add a phosphate group at hydrogen's spot

fructose 1,6 bisphopshate is the product, but ATP is not

Aldolase is the enzyme in step number four, which catalyzes the cleave

the five-carbon splits to DHAP and GAP, eager to leave

this step necessary for the energy needed to survive

glyceraldehyde 3-phosphate is oxidized by NAD

the product is 1,3 bisphoglycerate includes a phosphate group that was free

next, a phopshate group is lost

ATP earned with the product 3-phopshoglycerate instead of a cost

step 8 rearranges the position so the phopshate group switches location

phopshoglycerate mutase catalyzes at this occasion

at 9, enolase removes water from PEP

creating phosphoenolpyruvate with no ATP fee

the enzyme pyruvate kinase works with hydrogen and ADP

pyruvate and 2 ATP being created at step 10 finally
