What is Metabolism | Anabolism | Catabolism

Definitions and about Metabolism, Anabolism and Catabolism are as follows. Metabolism: All the chemical reactions taking place within a cell are collectively called metabolism.  Metabolic processes are characterized as anabolism and catabolism. Anabolism: Those reactions in which simpler substances are combined to form complex substances are called anabolic reactions. Anabolic reactions need energy.  Catabolism: Energy is released by the breakdown of complex molecules into simpler ones; such reactions are called catabolic reactions. Anabolic and catabolic reactions go hand in hand in the living cell. Coordinated Metabolism: Complex molecules are broken down and the resulting smaller molecules are reused to form new complex molecules. Interconversions of carbohydrates, protiens, and lipids that occur continuously in living cells are examples of co-ordinated catabolic and anabolic activities. Get True Knowledge

Can we see an atom

Can we see an atom It is not possible to see the atoms, but the nearest possibility is its direct evidence with the help of the following techniques: Electron Microscope: An ordinary optical microscope is used to see the object of the size up to 500 nm. This microscope uses visible light.  The electron microscope uses beams of electrons. So it can measure the object of size nearly to the size of an atom. It can measure the size of an object more than 15 million times. X-Ray X-Ray diffraction pattern obtained from diffractometer has made us able to believe the existence of the atom Further study: Click it Get True Knowledge

It is usually said that we are living in the age of computers. You might see computers in homes, government and non-government organizations. You will observe that in our day to day work routine how much depends on computers. Almost all over the world, the utility bills (i.e. gas, electricity and telephone bills) are prepared by computers. Suppose you are doing shopping, suddenly you need money but your money is kept in a bank which is far away from the market. The question is how you will manage to get money from the bank. Some years back, it was impossible to get money from a bank account without going to the bank. But now computers make it possible. You might have a cash machine. This machine provides you with the facility of doing banking without going to the bank. Most of the shopping malls provide a facility to accept credit card instead of cash. All is about through computers... Another example is that you have watched cartoons. In past hundreds of drawings made for a moment of ...
