CATABOLISMS Meaning and
Definition
-
Catabolism is a biological process involved in the breakdown of complex molecules into simpler ones, resulting in the release of energy. It is a vital component of metabolism, which represents all the chemical reactions that occur within an organism to sustain life. Catabolism encompasses the chemical reactions responsible for the decomposition of large molecules, such as carbohydrates, lipids, and proteins.
In catabolic reactions, complex organic compounds are broken down through various enzymatic pathways into smaller molecules. These smaller molecules can then be further broken down and utilized as sources of energy or as building blocks for other essential molecules. The main purpose of catabolism is to provide energy for cellular functions, such as growth, repair, and locomotion.
Catabolism is a highly regulated process that occurs constantly in living organisms. Through the controlled degradation of complex molecules, cells are able to extract energy stored within chemical bonds. This energy is then used to perform cellular work and maintain the organism's overall metabolic balance.
Catabolism is essential for the survival of living organisms, as it allows them to obtain the necessary energy and nutrients needed for their proper functioning. Without catabolism, cells would not be able to acquire the energy required for various activities, leading to an inability to sustain life processes.
Common Misspellings for CATABOLISMS
Etymology of CATABOLISMS
The word "catabolism" comes from the Greek roots "kata" meaning "down" and "bolē" meaning "throw". The term was first coined in the late 19th century and is used to describe the metabolic process of breaking down complex molecules into simpler ones to release energy. The plural form of "catabolism" is "catabolisms".
