Acids, bases and salts are three main categories of chemical compounds. These have certain definite properties that distinguish one class from the other. Scientists like Lavoisier and Davy studied acids and bases in a scientific manner. Initially, Lavoisier believed oxygen to be..

The word 'Physics' comes from the Greek word 'phusis' meaning 'nature', introduced by the ancient scientist 'Aristotle'. Man has always been fascinated by nature. So, he questioned and sought answers for every phenomena nature could offer. The branch of science which is devoted to t..

. The inner membrane encloses a matrix, which is rich in proteins, lipids, ribosomes, RNA and one or two circular DNA molecules. The number of mitochondria in a cell varies considerably and depends on the mature of the cell. Cells with very high-energy requirements possess very ..

The different kinds of micromolecules and macromolecules that we have studied so far occur in the cell dissolved in solution or as suspensions in a colloidal state. Alternatively, they may be assembled into subcellular components like cell membrane, cytoplasm and cell orga..

Introduction - The different kinds of micromolecules and macromolecules that we have studied so far occur in the cell dissolved in solution or as suspensions in a colloidal state. Alternatively, they may be assembled into subcellular components like cell membrane, cytoplasm and ..

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...

>The individual fungal cells are bound by definite cell wall made up of chitin or cellulose or both. Chitin also called as fungal cellulose, is normally found in association with other compounds like proteins and lipids. The cell wall encloses protoplasts which are differentiated into pla..

We have discussed many dramatic effects of hormone, for instance, testosterone. Yet, its concentration in the plasma of adult human male is only 30 to 100 ng per ml. How can hormones in such tiny quantities have such widespread and selective actions? Unlike catecholamine and peptide hormones, ster..

In carrier mechanism, activated ions combine with carrier proteins and from ion carrier complex. This complex moves across the membrane and reaches the inner space by the expenditure of energy. Within the cytoplasm, the complex breaks to release the ions. The carrier moves out o..

Question: Tick the wrong choice: Plasma or cell membrane is ____. 1. outer covering of each cell 2. made of lipids and proteins 3. superheated gases 4. a mechanical barrier for the protection of inner cell contents Answer: ..
