Is catabolism the process that combines smaller molecules to create larger molecules?

Catabolism refers to metabolic processes that break down larger molecules into smaller units, releasing energy in the process. This is crucial for the generation of energy that cells require for various functions, including growth, reproduction, and maintenance of cellular properties. The correct answer indicates an understanding that catabolic processes are about degradation rather than synthesis.

In contrast, anabolism is the actual process that involves combining smaller molecules to create larger, complex molecules, such as proteins, nucleic acids, and polysaccharides. This anabolic activity requires energy, often utilizing the energy generated from catabolic processes.

Understanding these definitions clarifies why the assertion that catabolism combines smaller molecules is incorrect, leading to the conclusion that the statement is false.
