Which organs produces and secretes enzymes that are essential for proper digestion?

Salivary glands - saliva to convert starch into sugar.

Stomach - (1) hydrochloric acid - to kill the bacteria entering the stomach as well as to make the medium acidic for the action of pepsin. (2) mucus - neutralises the action of hydrochloric acid. (3) pepsin - digests proteins.

Liver - (1) bile juice - makes the medium alkaline for the action of pancreatic enymes. (2) bile salts - emulisify fats.

Pancreas - (1) trypsin - digests proteins. (2) amylase - digests carbohydrates. (3) lipase - digests fats.

Small Intestine - convert carbohydrates to glucose, fats to fatty acids / glycerol, converts proteins to amino acids.

An enzyme refers to a kind of protein found inside a cell. The enzymes result in the chemical reactions within the body. The function to accelerate the rate of chemical reaction in order to support life. The enzymes in the body assist in performing very essential functions. These comprise eradicating toxins, building muscle, and dissociating particles of food at the time of digestion.

Enzymes are needed for performing the proper function of the digestive system. Digestive enzymes are primarily produced in the stomach, pancreas, and small intestine. However, even salivary glands generate digestive enzymes in order to dissociate the molecules of food at the time of chewing.

There are three prime kinds of digestive enzymes, which are classified on the basis of the reactions they catalyze. These are protease, amylase, and lipase.
