Identify the option that indicates the correct enzyme that is secreted in location (i), (ii) and (iii).

Q.) Identify the option that indicates the
correct enzyme that is secreted in location
(i), (ii) and (iii).

(a) (i)-lipase, (ii)-trypsin, (iii)-pepsin

(b) (i)-amylase, (ii)-pepsin, (iii)-trypsin

(c) (i)-trypsin, (ii)-amylase, (iii)-carboxy￾lase

(d) (i)-permease, (ii)-carboxylase, (iii)-ox￾idase

Ans. (b) (i)-amylase, (ii)-pepsin, (iii)-trypsin

Explanation: The digestion of food begins in
the mouth, marked as (i), as saliva contains an
enzyme called salivary amylase that breaks
down starch which is a complex molecule to
give sugar.
In the stomach marked as (ii), the gastric
glands present in its wall release hydrochloric
acid, a protein digesting enzyme called pepsin,
and mucus.
The enzyme trypsin secreted by pancreas
digests proteins.
