I became quieter, more organized and I finally stopped losing my keys. 1  I started taking ADD medication relatively late in life, at least for a millennial. I was 20, an honors student at a good university and I'd made it through my relatively successful academic career without being medicated.
(Science: Biochemistry). A catalyst or a chemical produced by cells to generally speed up specific chemical reaction without changing the chemical reaction at the end of the reaction.upplement. Enzyme is usually a protein molecule with a characteristic sequence of amino acids that fold to produce a specific three-dimensional structure, which gives the molecule unique properties. Other molecule with catalytic activity is ribozyme, an enzyme made of RNA rather than protein.
Enzymes are biological molecules that catalyse (speed up) chemical reactions. Enzymes are specificâthey will only work on particular molecules. For example, the enzyme sucrase will only bind with and break bonds in sucrose, not any other type of sugar.nother characteristic of enzymes is that they can be re-used over and over again. A single enzyme will typically catalyse around 10,000 chemical reactions per second. This means that only a tiny amount of enzyme is needed to have a huge effect on a reaction.
