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

Why We Need Computers?

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 ...

Ions | Types of Ions | How Ions Formed | Cations, Anions

Definition:                 A molecule, atom or species having a positive or negative charge is called an ion. Types of Ions.                      Ions are two types a) Positive Ions or Cations  b) Negative Ions or Anions a) Positive Ion or Cation:                                          A species which has a positive charge is called positive ion Cation. When atoms lose one or more electrons, positive ions are formed. A sufficient amount of energy is supplied to a neutral atom, then the atom loses an electron to form a positive ion. For this reason, the formation of a positive ion is an endothermic process.         A     + Energy ---------------------> A     +    1e  =  +ve Cations may have +1, +2, +3, +4 charge...
