2. Biochemistry n Science concerned with the chemical basis of life n Functional definition - Science concerned with the chemical constituents of living cells and with the reactions and processes they undergo.

3. Biochemistry (continued) n Biochemistry is the study of the molecular events that correspond to chemical changes in living cells n It includes these areas –Structural components –Movement of substrates, wastes and organelles within the cell –*Metabolism of the cell

4. Biochemistry Encompasses n Cell Biology n Molecular Biology n Major Objectives of Biochemistry – to completely understand at the molecular level, all chemical processes associated with living cells –The study of biochemistry has proven that there is a great deal of conservation of the basic biochemical activities of all cells.

5. Why study biochemistry n Biochemistry is essential to all life sciences –Physiology –Microbiology –Immunology –Pathology n Normal biochemical processes are the basis of health

6. The “Typical” Eukaryotic Cell n Segregation of biochemical function n See table of organelles and major functions
