Identify the option that indicates the correct enzyme that is secreted in location A, B and C.
(A) (i)-lipase, (ii)-trypsin, (iii)-pepsin
(B) (i)-amylase, (ii)-pepsin, (iii)-trypsin
(C) (i)-trypsin, (ii)-amylase, (iii)-carboxylase
(D) (i)-permease, (ii)-carboxylase, (iii)-oxidase
Answer -
Let’s check all 3 - (i), (ii) and (iii)
-
For (i)
- Location of (i) has
saliva
.
And saliva secretes an enzyme called amylase.
It breaks down starches present in our food into sugars which are easier to digest.
-
For (ii) -
Location of (ii) is
stomach
.
The digestion in the stomach is taken care of by the gastric glands present in the wall of the stomach. These release hydrochloric acid, a protein digesting enzyme called pepsin , and mucus.
-
For (iii) -
Location of (iii) is
pancreas
.
The pancreas secretes pancreatic juice which contains enzymes like trypsin for digesting proteins and lipase for breaking down emulsified fats.
So, the correct answer is (b)
