    Term:

    Which of the following correctly states the relationship between anabolic and catabolic pathways? (eText Concept 8.1) The flow of energy between catabolic and anabolic pathways is reversible. Energy derived from catabolic pathways is used to drive the breakdown of organic molecules in anabolic pathways. Catabolic pathways produce usable cellular energy by synthesizing more complex organic molecules. Anabolic pathways synthesize more complex organic molecules using the energy derived from catabolic pathways. Degradation of organic molecules by anabolic pathways provides the energy to drive catabolic pathways.

    Definition:

    Anabolic pathways synthesize more complex organic molecules using the energy derived from catabolic pathways.
