Question

What is common among amylase, rennin &
trypsin?
(a) They are all proteins
(b) They are proteolytic enzymes
(c) They are produced in stomach
(d) They are act at pH lower than 7

Answer 1

Explanation:

Amylase, renin, and trypsin are three classes of enzymes. Being enzymes, all three of them are proteinaceous in nature. Also, both renin and trypsin have roles in the digestion of proteins. Renin is secreted by the gastric glands, while trypsin is secreted by the pancreas. Amylases are found in saliva and pancreatic juice and acts on carbohydrates.

So, the correct answer is 'these all are proteins'.

hope it helps..

Answer 2

Answer is option 1

Reason:

Option 2 is incorrect because amylase is an enzyme which acts on carbohydrates not on proteins.

Option 3 is incorrect because trypsin is not produced in stomach.

Option 4 is incorrect because all of them do not act in acidic medium (pH less than 7)
