Step 1
An endergonic step is one where the products of that step have higher energy than the reactants of that step. In a reaction energy diagram, this means the energy level goes up from left to right for each individual step. Let's analyze each option: **Option Show more…

The overall reaction depicted by this energy diagram is: (A) endergonic, because point B is higher than point A. (B) endergonic, because point $C$ is higher than point $A$. (C) exergonic, because point D is higher than point E. (D) exergonic, because point A is higher than point E.
