Which of the following describes catabolism?

Catabolism is a vital metabolic process characterized by the breakdown of larger molecules into smaller units. This process is essential for the release of energy needed for various biological functions. During catabolism, complex molecules such as carbohydrates, proteins, and lipids are dismantled through a series of chemical reactions, resulting in the release of energy components that cells can utilize.

Choosing this answer emphasizes the role of catabolism in energy production, as it not only aids in the degradation of significant biological molecules but also provides substrates that can be further utilized in processes such as cellular respiration. As such, understanding catabolism is crucial for grasping how energy is derived from food and how it is utilized within the body.
