• Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions. The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.

Various enzymes which catalyses different convertions are-

• Diastace converts $Starch\to maltose$
• Pepsin converts $Proteins\to peptones$
• Ptyalin converts $Starch\to sugar$
• Zymase converts $Glucose\to ethylalcohol$
  
• Invertase converts $Canesugar\to Glucose+Fructose$
