Anabolism And Catabolism

Anabolism

Anabolism is one of the processes in metabolism. It is a constructive process. It is defined as simple molecules that combine to form complex molecules or the generation of complex molecule from simple molecules. It usually requires energy. This process produces complex molecules that can be used to store energy. It is the reverse process of catabolism. The energy used here is derived from the catabolic reactions. Energy for these reactions can be stored in the form of Adenosine Tri Phosphate (ATP) molecule.

Example

Carbohydrates and proteins are the molecules which results from the anabolic reaction.

Catabolism

It is a destructive process in which break down of complex molecules and formation of simple molecules takes place. This process proceeds with release of energy. The released energy acts as a driving force for the catabolic reaction. These reactions are catalyzed by enzymes.

Example:

Digestion is a process in which macromolecules like proteins carbohydrates are broken down into their simple molecules like amino acids and sugars etc.

Note: Two processes namely anabolism and catabolism constitute the process called metabolism. Metabolism is the sum or total of all chemical reactions in a living organism (combines both anabolic and catabolic process)



Most people use the term "metabolism" incorrectly for either anabolism orcatabolism: ... Catabolism is the breaking down of things - a series of chemical reactions that break down complex molecules into smaller units; catabolic processes usually release energy

Anabolism: The buildup of complex organic molecules from simpler ones, reactions are called anabolic or biosynthetic. They involve dehydration synthesis (release water) and are endergonic.

Catabolism: The breakdown of complex organic molecules into simpler ones. Reactions are called catabolic or degradative reactions, they are usually hydrolytic reaction and are exergonic

Metabolism can be simply defined as the set of biochemical processes that occur in an organism to sustain life. It can then be divided into two categories, processes that break down (catabolic) and processes that build up (anabolic). Anabolic VersusCatabolic.

Anabolism is the opposite of catabolism, for example, synthesizing glucose is an anabolic process whereas the breaking down of glucose is a catabolic process. ...Anabolism requires the input of energy, which can be described as an "uphill" (energy intake) process.

ATP not only provides energy to your cells, it also allows anabolic processes to occur. Anabolism is the reverse of catabolism, since these reactions build large biomolecules from smaller ones. And the molecules that are produced are the same types as what you find in food, such as carbohydrates and proteins.
