Question

Mention one point difference between pepsin and trypsin.

Answer 1

Hint: Enzymes are proteinaceous compounds which function as biological catalysts and help in accelerating the rate of reaction.

Complete Answer:

Sl.No	Pepsin	Trypsin
1.	It is an enzyme which is secreted by the stomach.	It is an enzyme secreted by pancreas.
2.	It is involved in digestion of proteins which are found in ingested food.	It also helps in digestion of partially digested proteins in the stomach and then converts them into dipeptides.
3.	It is secreted as an inactive zymogen known as pepsinogen.	It is secreted as an inactive form known as trypsinogen.

The one point difference between pepsin and trypsin is that pepsin is secreted in the stomach and acts only under acidic condition and trypsin is secreted in pancreas and acts under alkaline condition.

Additional information: The process of digestion involves many enzymes, a few of the enzymes are,
1) Lipase - It is secreted in the small intestine and is involved in breaking down fats.
2) Salivary amylase - It is secreted in the mouth and helps in digestion of starch present in the food.
3) Chymotrypsin - It is secreted in the pancreas and helps in digestion of proteins into dipeptides.
4) Lactase - It is secreted in the small intestine and helps in converting lactose into glucose.

Note: The one point similarity between pepsin and trypsin is that they are both involved in breaking down of proteins by breaking the bonds which are present between amino acids.
