Why are polymerization reactions endergonic?

Answer by  Brian5019 (40)

Polymerization typically requires some form of energy for elongation of the involved monomers. Let's take DNA polymerization as an example. DNA polymerase, which is an enzyme responsible for extending the DNA chain, utilizes triphosphate nucleotides to fuel the reaction. Since endergonic literally means "putting work into," polymerization reactions can be described as being endergonic.

Polymerization entails joining two or more molecules together which normally entails some sort of energy to complete. Endergonic means that the reaction requires energy.
