Answer 2

$\large{\underline{\underline {\pmb{\sf{\red{Answer:}}}}}}$

• Enzymes are a group of catalysts functioning in biological system. They are usually proteinaceous substances produced by a living cell that catalyse biochemical reactions without themselves being changed in the process.

• Salivary amylase is an enzyme of our digestive system which converts starch into maltose, isomaltose and small dextrins called alpha dextrins.
