Question

hs unit 2.1 cell energy and photosynthesis quiz 2025 (cor which of the following best describes the difference between anabolic and catabolic reactions? anabolic reactions break down molecules to release energy, while catabolic reactions build complex anabolic reactions require energy to build complex molecules, while catabolic reactions release ene both anabolic and catabolic reactions release energy by breaking down molecules. both anabolic and catabolic reactions require energy to build molecules.

Explanation:

Anabolic reactions are endergonic, meaning they require energy input to build complex molecules from simpler ones. Catabolic reactions are exergonic, breaking down complex molecules to release energy.

Answer:

Anabolic reactions require energy to build complex molecules, while catabolic reactions release energy by breaking down molecules.
