enzyme molecules react with reactants to produce substrate molecules

Enzyme Catalysis - Enzymes are macromolecules, usually proteins, produced in living systems, which act as catalysts in physiological reactions. The striking characteristics of enzymes are their catalytic power and specificity. Enzymes have immense c..

Any chemical reaction requires a certain amount of energy to get initiated. This is called activation energy. Most of the molecules in a substrate have average kinetic energy, some have high energy and some have low energy. Under normal conditions of temperature only molecu..

Laws of Chemical Combination With the development of more scientific ideas on elements, compounds and mixtures, people began to probe into how and why substances react. French chemist A. Lavoisier laid the foundation to the scientific investigation of matter by describing that substan..

Summary The law of conservation of mass states that the masses of the reactants and products remain unchanged. The law of constant proportions states that all pure specimens of a compound always contain the same elements combined together in the same proportion by weight. Accor..

Enzymes get denatured at very high temperatures, above 65 0 C. This denaturing occurs due to breakdown of the protein molecule..

Suppose a tuning fork vibrates with a frequency 540 cycles per second. If the vibration displaces air molecules by a maximum of 0.4 mm, then write the possible equation for the sound wave produced. => sin(1080 π x ) or (0.4)sin(1080 π x ) or (0.4)sin(540 π x ) or sin(54..

Gene Regulation in Prokaryotes - Bacteria cells can regulate the synthesis of enzymes in such a way that the enzymes are produced only when the substrates which these enzyme utilise are present in the ce..

It was suggested by Emil Fischer in 1894. According to this view, the enzyme molecule operates by chemically uniting with the substrate molecule, forming an enzyme-substrate complex. The enzyme molecule provides a uniquely struc..

>Peptiglycons are found in the cell walls of prokaryotic cells. Proteins are polymers of aminoacids arranged in a specific sequence which is decided by the genetic code present in the DNA molecule. The polypeptide chain in a protein may be straight (primary structure) or may form helical coils..
