Thus, metabolism is necessary for growth, movement and different cellular tasks. A specific set of hormones and regulatory enzymes control the anabolic and catabolic pathways. Therefore, anabolism and catabolism are enzyme-catalyzed reactions. This post discusses the key differences between anabolism and catabolism, along with the comparison chart, definitions, and examples.
The biosynthetic metabolic phase involves a set of enzyme-catalyzed reactions constructing biomolecules or macromolecules from simple molecules. Anabolism is an endergonic process requiring energy input.
Anabolic reactions are non-spontaneous ,i. It converts kinetic energy into potential energy. Anabolism is necessary for cell growth and development. It involves condensation and polymerization reactions, as small molecules condense or polymerize into a large biomolecule.
It refers to the metabolic process that involves a set of enzyme-catalyzed reactions destructing large biomolecules or macromolecules into simple or micromolecules. Catabolism is an exergonic reaction releasing energy in the form of adenosine triphosphate. Catabolic reactions are generally spontaneous , which means cells can utilize the released energy in various forms. It transforms potential energy into kinetic energy.

Catabolic pathways involve the degradation or breakdown of complex molecules into simpler ones.
Molecular energy stored in the bonds of complex molecules is released in catabolic pathways and harvested in such a way that it can be used to produce ATP. Other energy-storing molecules, such as fats, are also broken down through similar catabolic reactions to release energy and make ATP Figure 1.
Figure 1. Anabolic enzymes catalyze anabolic reactions that synthesize larger complex molecules from smaller units while catabolic enzymes catalyze catabolic reactions that break down larger complex molecules into smaller units.
So, this is the key difference between anabolic and catabolic enzymes. Furthermore, reactions that are catalyzed by anabolic enzymes require energy, while the reactions that are catalyzed by catabolic enzymes release energy. The following infographic lists the differences between anabolic and catabolic enzymes in tabular form for side by side comparison.
Anabolic and catabolic enzymes are two types of enzymes that catalyze biochemical reactions in metabolism. Anabolic enzymes catalyze the biochemical reactions that involve synthesizing larger complex molecules from smaller units, while catabolic enzymes catalyze the biochemical reactions that involve breaking down larger complex molecules into smaller units.
Thus, this is the summary of the difference between anabolic and catabolic enzymes. Samanthi Udayangani holds a B. Degree in Plant Science, M. Your email address will not be published. Figure Anabolic Enzymes.
