What are the 4 main enzymes involved in digestion?

The Role of Enzymes in the Digestive System

  • Amylase, produced in the mouth.
  • Pepsin, produced in the stomach.
  • Trypsin, produced in the pancreas.
  • Pancreatic lipase, produced in the pancreas.
  • Deoxyribonuclease and ribonuclease, produced in the pancreas.

What are the three types of digestive enzymes?

Types of enzymes

  • Amylase breaks down starches and carbohydrates into sugars.
  • Protease breaks down proteins into amino acids.
  • Lipase breaks down lipids, which are fats and oils, into glycerol and fatty acids.

How are enzymes used in digestion?

Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

Which enzymes are involved in digestion?


  • amylase and other carbohydrase enzymes break down starch into sugar.
  • protease enzymes break down proteins into amino acids.
  • lipase enzymes break down lipids (fats and oils) into fatty acids and glycerol.

What is an enzyme structure?

Enzymes are made up of amino acids which are linked together via amide (peptide) bonds in a linear chain. This is the primary structure. The resulting amino acid chain is called a polypeptide or protein. The specific order of amino acid in the protein is encoded by the DNA sequence of the corresponding gene.

What are the classification of enzymes?

Enzymes are classified into six categories according to the type of reaction catalyzed: Oxidoreductases, transferases, hydrolases, lyases, ligases, and isomerases.

What are the features of enzymes?

Some characteristics of enzymes are as follows:

  • Enzymes are highly specific for a particular substrate.
  • Enzymes remain unchanged during the reaction itself.
  • Enzymes are very efficient, catalyzing about 1-10,000 molecules of substrate per second.
  • Enzymes do not affect the equilibrium constant, or Keq.

What are enzymes describe their classification and nomenclature?

The first number represents enzymes that are classified according to the mechanism of enzymatic reaction. According to the type of reactions that the enzymes catalyze, enzymes are classified into seven categories, which are oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, and translocases.

What are enzymes name one enzyme of a digestive system and write its function?

Different Types of Digestive Enzymes Amylase Enzyme: They break down starches and carbohydrates into sugars. Protease Enzyme: it breaks down proteins into amino acids. Lipase Enzyme: It breaks down lipids, which are fats and oils, into glycerol and fatty acids. Nuclease Enzyme: They break nucleic acid into nucleotides.
