Catabolism is the process by which large molecules such as lipids, proteins, polysaccharides and nucleic acids are broken down into smaller molecules such as fatty acids, amino acids, monosaccharides and nucleotides, respectively, to release energy.
During this process, cellular wastes such as urea, carbon dioxide, acetic acid, ammonia and lactic acid are also produced. These residues are produced by the oxidation process which also results in the release of chemical free energy. Most of this energy is used to drive the synthesis of ATP (adenosine triphosphate).
Catabolism creates an important set of pathways as it provides the chemical energy needed for cell growth, remodeling and maintenance. There are many examples of the process of catabolism such as the citric acid cycle, glycolysis, fat breakdown into fatty acids, and body protein fragments to utilize various types of amino acids as substrates for gluconeogenesis.
Many hormones such as glucagon, adrenaline, cortisol and catecholamines regulate catabolism. Other hormones that contribute to the process of catabolism are hypocertin, cytokine and melatonin.
Anabolism is a natural process in which complex molecules are formed from smaller units. These reactions require energy and use adenosine triphosphate (ATP) to operate at normal rates. Instead, anabolism is a catabolism that destroys complex molecules into simple substances that are then used in breathing.
However, it is important to remember that anabolism is powered by catabolism and that the balance between these two processes is important to carry out metabolic reactions in one's body.
There are certain anabolic hormones such as anabolic steroids, testosterone, estradiol, insulin, IGF1 and growth hormones. Newly discovered hormones include melatonin, hypocretin and orexin. Anabolic steroids are also synthesized outside of the human body and injected by professional athletes to stimulate muscle growth and protein synthesis.
Anabolic process is very important because it helps build tissues and organs. Examples of anabolic processes include mineralization and bone growth and increased muscle mass. These processes also help increase the size of the body by involving the synthesis of complex molecules.
In short, anabolism can be defined as a set of metabolic processes and bio-chemical reactions that help produce complex components of smaller units. On the other hand, catabolism is also a metabolic process that can help break down larger molecules such as lipids and proteins into smaller units such as fatty acids and amino acids. In other words, anabolism helps you grow bigger and stronger while catabolism can lead to fat loss and weight loss.
