Once an enzyme has converted substrates into products, the active site reverts back to its original form. true or false?

That is True.

Enzymes are macromolecular biological catalysts which accelerate chemical reactions.

Enzymes catalyze biochemical reactions involving the substrate. Substrate bonds with the enzyme active site, forming the enzyme-substrate complex. The substrate is converted into one or more products, which are then released from the active site of the enzyme. The active site then reverts back to its original form and it is free to accept another substrate molecule.

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.
