Biochemistry, called biological chemistry, the study of chemical processes within and relating to living organisms. Biochemical processes give rise to the complexity of life. All areas of the life sciences are being uncovered and developed by biochemical methodology and research. Biochemistry focuses on chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells, which in turn relates greatly to the study and understanding of tissues, organs, and organism its structure and function. A living system grows, sustains and reproduces itself. The most amazing thing about a living system is that it is composed of non-living atoms and molecules. The pursuit of knowledge of what goes on chemically within a living system falls in the domain of biochemistry.
