active electronic components

Show how nitrogen shares a covalent bond with hydrogen in the formation of ammonia (NH 3 ). Are all electrons involved in the bonding? Give the Lewis structure of the covalent bond als..

If the above activity is repeated with another wire or a torch bulb, the current values are found to be different in each case. This shows that the current through the circuit is not decided by the battery but by the component through which it passes. Some materials allow larger..

The metabolic pathway through which the electron passes from one carrier to another, is called the electron transport system. Electron Transport System (ETS) in Mitochondrion The electron transport system occurs in the inner membrane of the mitochondria. The ..

Electron transport chain refers to the light driven reactions of photosynthesis. They were first formulated in 1939 by Robert Hill. The two photosystems are connected in series with each other by the components of electron transport system. The reaction centres become ..

This series is an important tool that helps in predicting many electrochemical reactions. All metals placed above hydrogen will displace hydrogen from acids while those below it do not displace hydrogen from acids. Elements with high electropositive or electronegative power are highly reactiv..

This theory was proposed by H. Lundegardh, who suggested that anions could be transported across the membrane by cytochrome system. Energy is supplied by direct oxidation of respiratory intermediates. Diagrammatic representation of cytochrome pump hypothesis On salt absorption, anions (A - )..

It is a component of nucleic acid, phospholipids, ATP, nucleoprotein, NAD, NADP and a number of co-enzymes. Since the young cells are the seat of maximum metabolic activities, maximum phosphorus is found in the meristems, fruits and seed..

Atomic Number and Atomic Mass - The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleu..

Soil can be defined as the uppermost crust of earth mixed with organic material and in which animals and microorganisms live, and plants grow. The word soil is derived from a Latin word solum meaning ground. It is a stratified mixture of inorganic and organic materials, both of which are products o..
