What are the opposite words for anabolism?

Anabolism is the process by which the body builds up complex molecules from simpler ones; it is a vital part of metabolism. The opposite of anabolism is catabolism, which is the breakdown of complex molecules to simpler ones to produce energy. While anabolism is often associated with growth and repair, catabolism is associated with the degradation of materials in the body. Another antonym for anabolism is katabolism, which is similar to catabolism in its process of breaking down molecules for energy. Both these processes are essential for maintaining a healthy body, but they perform opposite functions. An imbalance in either process can result in health problems.
