Catabolism is the part of the metabolism responsible for breaking complex molecules down into smaller molecules. The other part of the metabolism, anabolism, builds simple molecules into more complex ones.
What are examples of catabolism? Essentially, during catabolism, complex molecules like, proteins, polysaccharides, and fats are broken into small molecules like amino acids, monosaccharides, and fatty acids.
Catabolism is the set of biochemical reactions that break down complex molecules into simpler ones. Catabolic processes are thermodynamically favorable and spontaneous, so cells use them to generate energy or to fuel anabolism. Catabolism is exergonic, meaning it releases heat and works via hydrolysis and oxidation.
Some examples of the catabolic processes include glycolysis, the citric acid cycle, the breakdown of muscle protein in order to use the amino acids as substrates for gluconeogenesis, the breakdown of fat in adipose tissue to fatty acids, and oxidative deamination of neurotransmitters by monoamine oxidase.
The digestion of food is a key example of catabolism. During digestion, large, complex food molecules are broken down into smaller components, and energy is released as a result. For example: Complex carbohydrates are broken down into simple sugars. Proteins are broken down into amino acids. Lipids are broken down into fatty acids and glycerol.
Catabolism is the body’s process of breaking down molecules to release and produce energy. What are the 5 Examples of Catabolism? Examples include glycogen breakdown, protein degradation, lipid oxidation, cellular respiration, and digestive processes.
