Question

How many molecules are in the human body?

Answer 1

Hint: Human body is made up of various organic molecules and each of these molecules has a specific function in the human body.

Complete answer:
1)Humans are entirely made up of cells and that is why the cell is also known as the basic structural and functional unit of life. These cells although very small in size and a single cell cannot be even observed by a naked eye but still contain a large number of molecules.

2)Approximately, a cell is 65% water which is also a molecule, and the rest of the cell is occupied by different ionic substances. The different molecules present in the human body include proteins, RNA, DNA, carbohydrate, lipid, and water.

3)According to different experiments and research, it is concluded that a human body contains 61% water and hence forms a major part of the human body, and the human body has an almost similar amount of fat and proteins, they both occupy 16% of the body, that is total 32% and human body contain 6% minerals such as sodium, potassium, phosphate and other ions and only 1% of carbohydrates.

Note: The diet and nutrition in humans varies according to age and different factors, hence the number of molecules in the human body also depends on the size and age of the human. For example, if we compare the number of molecules present in a child whose age is 1-2 years and an adult of age 24-25, the number of molecules will show a large difference.
