Metabolic reaction is actually a chemical system. There are different types of metabolic reactions which can be possessed inside a human body. The word ‘Metabolism’ has come from the Greek work ‘Metabole’ which means ‘change’.
The process of metabolism is required for sustaining life. This is actually a process of creating energy and synthesizing the elements of a body. In other words, it is a process of producing special substances inside the body. In a word, Metabolism means the sum total of all the chemical and physical changes occurs in a body.
Different animals have different type metabolic speed. The birds have very high rate of metabolic speed. The metabolic speed persuades the required food for the organs and determines the way to obtain the foods.
Different experts can show different types of metabolic reactions. Basically, there are two types of metabolic reactions. These two are:
1. Anabolic process.
2. Catabolic process.
Anabolic process, another name ‘Anabolism’ is actually a constructive metabolic process. It comes from the Greek word ‘ana’ and ‘ballien’. ‘Ana’ means ‘Upward’ and ‘ballien’ means ‘to throw’. It is actually such a process through which the body builds up or synthesizes the molecules. Among the types of the metabolic reactions, this one is treated as the constructive one. This process helps the body to grow new cells. This process can be compared with the construction a building with bricks.
This process uses monomers and then creates polymers. Monomers are small molecules. So, in anabolic process small elements make a big one. Mineralization of bones is the example of anabolic process. The anabolic process uses anabolic steroids for completing the process. These anabolic steroids can stimulate the growth of muscle, insulin and protein synthesis.
This is just opposite to the process of anabolism, known as process of destruction! This word has come from the Greek word, ‘kata’ which means ‘downword’ and ‘ballein’ means ‘to throw’. It is the process through which large elements breaks into small elements. The catabolism process is controlled by various signals. Normally, these signals are known as hormones. Among the types of metabolic reactions the catabolism is an important one as it supplies the required energy for the growth and maintenance of the sales. Recently, hormones with catabolic effects are discovered recently. Some catabolic hormones create anti-catabolic effects on the muscles.
Both of the processes are organized by metabolic pathways. Enzymes play an important role in this process. All the types of metabolic reactions are spontaneous reactions occurred step by step. Enzymes work as catalysts in this process as they quicken the whole process. It also acts as the regulator of the metabolic pathways. These occur because of the response of the cells’ environment and the signals received from other cells. By the process of metabolism, the body determines the nutrition as well as the poisonous elements. For example, hydrogen sulfide is good and nutritious for the prokaryots but not for the animals.
So, these are the types of metabolic reactions. The metabolic reaction is still an important subject of research for the scientists.
