Answer

Catabolic reactions have negative $ΔG$, corresponding to increased entropy and decreased enthalpy. Anabolic reactions have positive $ΔG$, corresponding to decreased entropy and increased enthalpy.

Work Step by Step

Catabolic reactions are exergonic reactions that have a negative $ΔG$. In contrast, anabolic reactions are endergonic reactions that have a positive $ΔG$ value.
