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 proteins that catalyze (i.e. accelerate) chemical reactions.[1] In enzymatic reactions, the molecule s at the beginning of the process are called substrate s, and the enzyme converts them into different molecule s, the products. Enzymes. Enzymes are catalysts.Most are proteins. biological macromolecule that acts as a catalyst. Most enzymes are proteins, but certain RNAs, called ribozyme s, also have catalytic activity. Enzymes and Metabolism. 1) Enzymes are proteins which catalyze reactions in cells.
