Katabolizam

Katabolizam refers to the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or are used to synthesize other molecules. These pathways are considered destructive or catabolic, as they break down complex molecules. In essence, katabolizam is the process of breaking down large molecules such as carbohydrates, fats, and proteins into simpler components like glucose, fatty acids, and amino acids. This breakdown releases energy, which is then stored in the form of adenosine triphosphate (ATP). ATP is the primary energy currency of the cell, powering various cellular processes. For example, the breakdown of glucose through glycolysis is a key katabolizam pathway that yields ATP. Similarly, the breakdown of fatty acids through beta-oxidation also produces significant amounts of ATP. Proteins are broken down into amino acids, which can then be used for energy or to build new proteins. The waste products of katabolizam, such as carbon dioxide and water, are then eliminated from the body. This process is crucial for providing the energy needed for all life activities, from muscle contraction and nerve impulse transmission to cell growth and repair. Without katabolizam, cells would not have the energy to function.
