What is a characteristic of catabolism?

Catabolism is a metabolic process that involves breaking down complex molecules into simpler ones. This process is essential for energy release, as it allows organisms to tap into stored energy from nutrients, such as carbohydrates, fats, and proteins. During catabolic reactions, energy is released, which can then be used for various cellular activities, including maintaining cellular functions and driving anabolic processes, which build new molecules from simpler ones.

The characteristic of releasing energy from food specifically highlights the role of catabolism in metabolism. This energy is crucial for sustaining life and powering various biological functions within an organism. In this context, the correct answer emphasizes the fundamental nature of catabolic processes in energy metabolism.
