Question

What is common amylase, remain and trypsin?
A) These are produced in the stomach.
B) They act as a $pH$ lover than $7$.
C) These all are protein.
D) These all are proteolytic enzymes.

Answer 1

There are various enzymes in the digestive system. They act upon different substrates and digest them. There are different criteria for the smooth functionality.

Complete Answer:

1. Source- Among the $3$ enzymes, none is produced in strands of amylase and trypsin release from pancreatic juice and renin from Juxtaglomerular cells of heparin.
2. Basically, no enzyme is produced in the stomach. Only acidification is cloned through the action of $HCl$ $\left( {dil} \right)$ released from an oxyntic cell.
3. Environment- All the $3$ enzymes don’t satisfy the condition (B) as Trypsin acts in the alcoholic medium $pH$ $7$.
4. Function: All the $3$ enzymes don’t act upon the proteinaceous substrate.
   For example, only trypsin acts or protein, Amylase is an amylolytic enzyme that acts on carbohydrates. So, the option D is not true.
5. Biochemical nature: All the enzymes are protein with respect to their biochemical structure.

So the correct answer is option D.

Note: Through the smooth functioning of enzymes, the different food particles are digested. Increasing or decreasing the required conditions may vary the functioning of these enzymes, it may slow down the activity in some cases it may denature the enzymes.
