Chemicals in Medicine: Class 12

Chemicals in Medicine: Drugs compete with the natural substrate for their attachment to the active sites of enzymes. Such drugs are called competitive inhibitors. Some drugs do not bind to the enzyme’s active site. These bind to a different site of enzyme which is called allosteric site. This binding of inhibitor at the allosteric sites […]

Semiconductor Electronics: Materials, Devices, and Simple Circuits

Classification of solids on the basis of their conductivity(Semiconductor Electronics): On the basis of the relative values of electrical conductivity (σ) and resistivity (ρ = 1/σ), the solids are broadly classified as, Metals: Those solids which have high conductivity and very low resistivity. The value of conductivity for metals lies in between 102 to 108 […]

Dual Nature of Radiation and Matter

Electron Emission Radiation and Matter: The phenomenon of emission of electrons from the surface of a metal. The minimum energy needed by an electron to come out from a metal surface is known as the “work function” of the metal. It is denoted by f0 or W0 and measured in electron volt (eV). The electron […]
