Which site of an enzyme is called allosteric site?
Sites different from active site of enzyme where a molecule can bind and change the shape of the active site is called allosteric site.
What type of forces are involved in binding of substrate to the active site of enzyme?
During the catalytic action of an enzyme, enzyme hold the substrate for a chemical reaction. Active sites of enzymes holds the substrate molecule in a suitable position, so that it can be attacked by the reagent effectively.
Substrate bind to the active site of the enzyme through a variety of interactions. These forces are van der Waals' interactions, ionic bonding, hydrogen bonding or dipole-dipole interaction.
What is the commonality between the antibiotic arsphenamine and azodye?
Arsphenamine is also known as salvarsan. It is a synthetic organic arsenic compound that was previously used for treating syphilis. Arsphenamine possess $-$ As $=$ As $-$ linkage. Azo dyes are used to promote epithelial growth in the treatment of ulcers, burns, and other wounds. Many azodyes have anticoagulation action. Azo dyes possess $-\mathrm{N}=\mathrm{N}-$ linkage like arsphenamine which possess $-\mathrm{As}=\mathrm{As}-$ linkage.
