NEET BIOLOGY

Detailed explanation-1: -The enzyme, lactase (enzyme names often end in-ase) breaks lactose into its two monosaccharide components. Sucrose, or table sugar, is another common sugar composed of glucose and fructose, a five-sided molecule. In this lab, we will use the enzyme lactase to attempt to break down both of these disaccharides.

Detailed explanation-2: -Enzymes are named by adding the suffix-ase to the name of the substrate that they modify (i.e., urease and tyrosinase), or the type of reaction they catalyze (dehydrogenase, decarboxylase). Some have arbitrary names (pepsin and trypsin).

Detailed explanation-3: -You can often recognize that a protein is an enzyme by its name. Many enzyme names end with –ase. For example, the enzyme lactase is used to break down the sugar lactose, found in mammalian milk.

Detailed explanation-4: -Some commonly known examples of enzyme end with the suffix “ase” are the catalytic reaction of an enzyme named maltase react with substrate named maltose to produce glucose and enzymatic action of lactase on the substrate called lactose to produce glucose and galactose.

Detailed explanation-5: -Examples of the few enzymes without-ase names include: peptin, trypsin, and chrymotrypsin.
