Question

What about their names identifies amylase and B-galactosidase as enzymes? Since enzymes are neither used up nor generated in the reaction, they are not included as a substrate or product when writing a chemical reaction. They are usually written over the arrow to signify that they catalyze or enhance the rate of the reaction. Write out the equation for the hydrolysis of ONPG including the enzyme (by name and number). Write out the reaction for the hydrolysis of starch including the enzyme (by name and number).

Answer 1

1) Enzymes the proteinaceous substances which act as a catalyst for the conversion of a substrate into product.

There are many classes of enzyme.

International union of biochemistry and molecular science developed a universal criteria for the classification of enzyme.

The name of enzyme is derived from the the state or the reaction it catalyzes aided by suffix -ase.

Hear in the question amylase is the enzyme which converts starch into simpler sugar. It act on the glycosidic bond.

Beta galactosidase is the enzyme which converts beta galactoside into galactose. It is also known as lactase. Deficiency of this enzyme in adults leads to lactose intolerance.
