Gastric juice of infants contains
-
maltase, pepsinogen, rennin
-
nuclease, pepsinogen, lipase
-
pepsinogen, lipase, rennin
-
amylase, rennin, pepsinogen
C.
pepsinogen, lipase, rennin
Gastric juice of infants contains pepsinogen, lipase, rennin. It's pH varies from 7.5 and 8.5. Rennin is a proteolytic enzyme synthesised by stomach. Its role is to curdle or cogulate milk. Therefore, it is present in infants because they feed on milk but is absent in adults.
In the stomach, gastric acid is secreted by the
-
parietal cells
-
peptic cells
-
acidic cells
-
gastrin-secreting cells
A.
parietal cells
The parietal cells secrete HCl in the stomach.
One of the constituents of the pancreatic juice while poured into the duodenum in humans, is
-
Trypsinogen
-
chymotrypsin
-
trypsin
-
enterokinase
A.
Trypsinogen
Trypsinogen is the precursor form or zymogen of the pancreatic enzyme trypsin. It is found in pancreatic juice, along with amylase. lipase and chymotrypsinogen. It is activated by enteropeptidase which is found in the intestinal mucosa, to form trypsin.

Small intestine and active absorption |
Amino acids monosaccharides like glucose, electrolytes like Na+ are absorbed into the blood by active transport. Fructose and some amino acids are absorbed with the help of the carrier ions like Na+ by facilitated transport. Fatty acid and glycerol cannot be absorbed into the blood. They are first incorporated into small droplets called micelles, which move into the intestinal mucosa.
