Multiple Choice

Which of the following correctly states the relationship between anabolic and catabolic pathways?

Degradation of organic molecules by anabolic pathways provides the energy to drive catabolic pathways.

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.

The flow of energy between catabolic and anabolic pathways is reversible.

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

Verified step by step guidance

Understand the definitions: Anabolic pathways are involved in building up complex molecules from simpler ones, requiring energy input. Catabolic pathways break down complex molecules into simpler ones, releasing energy.

Recognize the energy flow: Catabolic pathways release energy by breaking down molecules, which is then used by anabolic pathways to synthesize complex molecules.

Identify the correct relationship: Anabolic pathways use the energy derived from catabolic pathways to synthesize more complex organic molecules.

Clarify the incorrect options: Degradation of molecules is a catabolic process, not anabolic. Anabolic pathways do not break down molecules; they build them up.

Conclude with the correct statement: Anabolic pathways synthesize complex molecules using energy from catabolic pathways, highlighting the interdependence between these two types of metabolic pathways.
