unit conversion

The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atom of 6 C 1 2 isotope. It can be shown that 1 a.m.u = 1.66 x 10 2 7 kg. According to Einstein, mass energy equivalence E = mc 2 Where m..

The cell is the fundamental structural and functional unit of living organisms. Cells need energy for active transport, to move molecules between the environment and the cells across cells or within cells. Cells obtain energy by oxidation of molecules like glucose. This oxidation takes pl..

If we rub our hands for a while, the hands become warm. Let us examine the process. Rubbing hands is mechanical work and in this process heat is generated. We can say heat energy is produced as a result of mechanical work. Let us examine another example - when you light a matchstick, you strike it ..

Enzymes are the biocatalysts of life. They are defined as biocatalysts synthesized by living cells. They are simple or conjugate protein and specific in action. At present about 300 enzymes are recognized and classified into six classes by International Union of Biochemistry (IUB). They are: Oxidor..
