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 An enzyme is a protein that acts as biological catalyst. A catalyst is a substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reactionâs activation energy. Temperature, pH, and regulatory molecules can affect the activity of enzymes.Chemical Reactions. 2.ubstrates bind to a part of an enzyme called the active site and remain bound to the enzyme until the reaction is complete, when the products are released. Temperature, pH, and regulatory molecules can affect the activity of enzymes. 1.
