Metabolism is a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organism.
Metabolism can be conveniently divided into two categories:
- Catabolism - the breakdown of molecules to obtain energy
- Anabolism - the synthesis of all compounds needed by the cells
- Metabolism is closely linked to nutrition and the availability of nutrients. Energy formation is one of the vital components of metabolism.
Nutrition, metabolism and energy:
Nutrition is the key to metabolism. The pathways of metabolism rely upon nutrients that they breakdown in order to produce energy. This energy in turn is required by the body to synthesize new proteins.
Essential nutrients supply energy and the necessary chemicals which the body itself cannot synthesize. Food provides a variety of substances that are essential for the building, upkeep, and repair of body tissues, and for the efficient functioning of the body.
Your diet needs essential nutrients like carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, and many other elements. The major elements are supplied in carbohydrates, lipids, and protein. In addition, vitamins, minerals and water are necessary.
The minerals in foods do not contribute directly to energy needs but are important as body regulators and play a role in metabolic pathways of the body.
Important minerals include:
Vitamins are essential organic compounds that the human body cannot synthesize by itself and must therefore, be present in the diet.
The chemical reactions of metabolism are organized into metabolic pathways. These allow the basic chemicals from nutrition to be transformed through a series of steps into another chemical, by a sequence of enzymes.
Enzymes are crucial to metabolism because they allow organisms to drive desirable reactions that require energy. Enzymes also allow the regulation of metabolic pathways in response to changes in the cell's environment or signals from other cells.
If you have a fast metabolism, you will lose weight faster. In order for you to have a faster metabolism you need to follow a healthy diet and do regular physical activities.
