At the molecular level all the different types of cells in living organisms are composed of certain chemical substances. The structure and function of the cell and its components are dependent on the molecular structure, arrangement and properties of these chemical constit..

The living cells contain specific macromolecules with a high molecular weight and a poor solubility. Generally in a cell, macromolecules are represented by polysaccharides, proteins, nucleic acids and enzymes. These compounds are formed by polymerisation of micromolecules such as su..

Every organism has a tendency to increase its entropy, which is very much in accordance with the second law of thermodynamics. In order to maintain its organisation at the molecular, cellular and organismic levels, every organism is forced to obtain energy from its surroundings..

Any chemical substance which has a molecular structure that closely resembles a substrate, can reduce or inhibit the activity of an enzyme. Such an inhibitor is called competitive inhibitor. This situation is comparable to a lock jammed by a key almost similar to the original one. fi..

The membrane bound receptors of insulin is a heterotetrameric protein consisting of four subunits, two -subunits protrude out from surface of the ell and bind insulin, and two -subunits that span the membrane and protrude into the cytoplasm...

Nucleic Acids - Nucleic acids are giant macromolecules having a complex structure and very high molecular weight. They are polymers of nucleotides and hence, described as polynucleotides. There are two types of nucleic acids found in a cell, namely deoxy ribose nucleic acid (DNA) and ribo..

These are esters of fatty acids with various types of alcohol. They are distinguished into fats and oils. Fats are esters of fatty acids and glycerol. A fatty acid is an organic acid with a hydrocarbon chain ending in a carboxyl (COOH) group. Most fatty acids have an even number of carbon atoms ran..
