Question

The branch of science which deals with the study of chemical processes within the body is
known as
A. Microbiology
B. Biotechnology
C. Biochemistry
D. None of the above

Answer 1

Hint: The study and the knowledge of the physical environment and the explanation of the natural mechanisms is known as 'science'. Science is divided into various branches. Each branch of science is concerned with specific functions and explanations of nature and it's laws. Among the various fields of science, the science of life forms and living processes is known as 'biology'. It is the story of evolution of living organisms on earth.

Complete answer:
The living world is full of amazing diversity of living organisms. There occurs a very vast diversity of habitats of organisms on earth. Each and every organism, whether small or large, visible or invisible, unicellular or multicellular plays a very important functional role in maintaining the equilibrium of nature.
The branch of science which includes the study of all types of microorganisms, whether unicellular or multicellular, is called microbiology. This includes the study of organisms which are usually invisible to the naked eye such as bacterias, viruses, protozoans, fungi and other microorganisms.
The branch of science which deals with techniques of using live organisms or enzymes from organisms to produce products and processes useful to humans is called biotechnology. Biotechnology is the integration of natural science and organisms, cells, parts thereof and molecular analogues for products and services. There are many chemical processes occuring in a living organism. All these chemical processes are essential for an organism to survive in its environment.
The branch of science that includes the study of all the chemical processes in a living organism is called Biochemistry. Biological chemistry of an organism determines its complexity of life. All the nutritional information of an organism can be studied through biochemistry.
Thus the correct answer is option C.

Note: Biochemistry is the branch of science which is used in laboratories on a large scale. It combines biological processes with the laws of chemistry. It is used to diagnose various clinical implications and is also used to treat these implications. The study of all the enzymes, proteins, carbohydrates and fats in the body of a living organism, is included under biochemistry of that particular organism.
