The two 3-carbon molecules in which glucose is split, are converted through a series of steps into the final 3-carbon molecule. during these later steps, molecule(s) of atp are made.

four (4)

Explanation:

The two 3-carbon molecules in which glucose is split are DIHYDROXYACETONE and GLYCERALDEHYDE 3-PHOSPHATE.

These two are ISOMERS and are converted through a series of five steps into the final 3-carbon molecule called PYRUVATE, CH3COCOO

During these later steps KNOWN as the PAYOFF phase (phase II) of glycosis, FOUR (4) molecules of ATP are made.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
