Question

Differentiate between essential and non-essential mineral elements?

Answer 1

Hint: The living organisms require several different types of organic and inorganic substances to use, sustain and grow by performing several biological processes. Some of these substances are required in small quantities but they are essential for carrying out different processes. Without the availability of the proper amount or quantity of these substances, the organism may face several deficiencies.

Complete answer:
The mineral elements are defined as the inorganic elements that are required by the body in smaller amounts in order to perform various functions. The mineral elements cannot be synthesized by the living organism and they have to be received from other sources such as soil, water etc. The mineral elements form an integral part of the organism as it is involved in the formation of bones, teeth, body fluids and tissues. They also form an important part of the enzyme system and help in normal functioning of the nerves.

The requirement of the mineral elements by the body depends upon a number of factors such as age, physiological state as well as the health condition. The body needs different types of minerals in different quantities. According to the amount that is required by the body, the mineral elements can be divided into essential and non-essential minerals.

Essential minerals are those types of mineral elements that are required by an organism for normal growth and development. These mineral elements are vital for overall development of the organism. Essential mineral elements are the most basic blocks that are necessary for every type of biological processes occurring in the organism. Some important essential elements are oxygen, carbon, hydrogen, nitrogen etc. constitutes about more than ninety percent of the human body. Apart from these elements, some other essential elements that are important for living organisms are calcium, sodium, iodine, iron, phosphorus, potassium, copper and zinc.

Whereas some other minerals elements are also found in the living organism in addition to the essential minerals elements. These elements can be synthesized by the body and are required in small amounts. Such types of mineral elements are known as non-essential mineral elements. This type of mineral does not play a significant role in meeting nutritional demands. Some of the non-essential elements are aluminium, arsenic, bromine, cadmium, barium etc.

Note: The body requires certain important mineral elements for normal functioning and development and they are known as essential elements while some other elements are also found in the body that are not needed or are synthesized by the body. The mineral elements that are readily synthesized in the body and are needed in small amounts are known as non-essential elements. The essential mineral elements cannot be synthesized by the organism and are provided by the natural sources such as air, water, soil and also by consuming plant foods.
