Verified step by step guidance

Understand the definitions: Endergonic reactions are those that require energy input and have a positive change in Gibbs free energy (ΔG > 0). Exergonic reactions release energy and have a negative change in Gibbs free energy (ΔG < 0).

Review the concept of catabolic reactions: Catabolic reactions involve the breakdown of molecules and are typically exergonic, meaning they release energy.

Analyze the statement 'All endergonic reactions are catabolic': Since endergonic reactions require energy input, they are not typically associated with catabolic processes, which release energy.

Consider the statement 'All exergonic reactions are spontaneous': Exergonic reactions, having a negative ΔG, are indeed spontaneous as they proceed without the need for additional energy input.

Evaluate the options: The statement 'All endergonic reactions are catabolic' is false because endergonic reactions are not associated with energy-releasing catabolic processes.
