Question

how are catabolic and anabolic reactions linked?
through potential energy
through disorder
through atp
through entropy

Explanation:

Catabolic reactions break down molecules and release energy, which is used to synthesize ATP. Anabolic reactions use ATP to build molecules. So, ATP links catabolic (energy - releasing) and anabolic (energy - consuming) reactions. Potential energy is a more general term and not the specific link. Disorder and entropy are related to the second law of thermodynamics but do not directly link these two types of reactions.

Answer:

through ATP
