What Is The Introduction Of Bio- Chemistry?

Bio chemistry is a branch of biology, which deals with the study of chemical components and the chemical process in living organisms. A basic knowledge of bio chemistry is essential for understanding anatomy and physiology, because all of the structures of an organism have bio chemical organization. For example, photosynthesis, respiration, digestion, muscle, and contraction can all be described in biochemical terms.

All living things are made of certain chemical compounds, which are generally classified as organic and inorganic. Most important organic compounds in living organisms are carbohydrates, proteins, lipids and nucleic acids. Among inorganic substances are water, carbon dioxide, acids, bases and salts.

The survival of an organism depends upon its ability to take some chemicals from its environments and use them to make chemicals of its living matter. For this reason, cells of every organism are constantly taking in new substances and changing the chemically in various ways i.e. building new cellular materials and obtaining energy of their needs, Life of an organism depends upon the ceaseless chemical activities in its cells. This chemical activity is maintained with a high degree of organization.

All the chemical reactions taking place with in a cell are collectively called metabolism. Metabolic processes are characterized as anabolism and catabolism. Those reactions in which simpler substances are combined to form complex substances are called anabolic reactions. Interco versions of carbohydrates, proteins, and lipids that occur continuously in living cells are examples of co-ordinate catabolic and anabolic activities.
