Question 1
1 / -0

Prorennin is secreted by

A
Zymogen cells

B
Sertoli cells

C
Islets of langerhans

D
Hepatocytes

Solution

Chief cells or Peptic cells (Zymogen cells) are usually basal in location in stomach wall and secrete gastric digestive enzymes as proenzymes or zymogens; pepsinogen and prorenin. Prorenin is secreted in young mammals. It is not secreted in adult mammals.
Question 2
1 / -0

Carbohydrate digestion occurs first in which structure?

A
Mouth

B
Intestine

C
Stomach

D
None of the above

Solution

The digestion of carbohydrates begins in the mouth. The salivary enzyme amylase begins the breakdown of food starches into maltose, a disaccharide.
Question 3
1 / -0

Find out the correctly matched pair.

A
Pepsinogen $$\rightarrow $$ Zymogenic cells

B
HCl $$\rightarrow $$ Goblet cells

C
Mucous $$\rightarrow $$ Oxyntic cells

D
Pancreatic juice $$\rightarrow $$ Salivary glands

E
Ptyalin $$\rightarrow $$ Acinar cells

Solution

Chief cells or Peptic cells (Zymogen cells) are usually basal in location in stomach wall and secrete gastric digestive enzymes as proenzymes or zymogens; pepsinogen and prorenin. The oxyntic or parietal cells in stomach secrete the acid hydrochloric acid. The acinar cells in pancreas secrete digestive enzymes. The goblet cells secrete mucous. The goblet cells are widely distributed throughout the alimentary canal. The saliva contains amylase called ptyalin.
Question 4
1 / -0

Kwashiorkor disease caused due to deficiency of

A
Protein

B
Fat

C
Sugar

D
Hormone

Solution

Kwashiorkor is a protein deficiency disease. It commonly affects infants and children between 1 to 3 year of age. The symptoms are underweight children, stunted growth, poor brain development, loss of appetite, anaemia, dermatitis on lower leg and face. Proteins are necessary for growth, repair of tissue and for body defence therefore adequate amount of proteins must be present in the diet. Daily requirement is 1 gm protein per kg body weight in adult and 2 gm protein per kg body weight in growing children. Important sources of protein in food are cereals, pulses, meat, fish, milk, groundnut, peas etc.
Question 5
1 / -0

Identify the false statement from the following.

A
Oesophagus does not secrete any enzyme.

B
Gall bladder is absent in horse.

C
Human teeth are thecodont.

D
There are two pairs of salivary glands in humans.

Solution

There are three main pairs of salivary glands: the parotid, the submandibular and the sublingual glands.
Question 6
1 / -0

Among mammals, a significant role in the digestion of milk is played by

A
Rennin

B
Invertase

C
Amylase

D
Intestinal bacteria

Solution

Gastric juice consists of gastric enzymes like pepsinogen, pro rennin, gastric lipase etc. Rennin is active in the childhood stage of mammals only. It converts milk into curd like substance (called clotting of milk) and then digests it. In adult stages, it is inactive. Rennin, acts on milk protein caseinogen. Caseinogen is a soluble protein. In presence of rennin, caseinogen gets converted into insoluble caseinate. This process is termed as curdling of milk. After becoming insoluble, milk can remain in the stomach for a longer time. Rennin is absent in human and clotting of milk is done by hydrochloric acid in humans.
Question 7
1 / -0

Chymotrypsin is produced by

A
Liver

B
Pancreas

C
Stomach

D
Duodenum

Solution

Chymotrypsin is a digestive enzyme, that breaks down proteins (i.e., it is a proteolytic enzyme; it can also be referred to as a protease). It is naturally produced by the pancreas in the human body.
Question 8
1 / -0

Pancreatic juice contain bicarbonate which is secreted by

A
Paneth cells

B
Goblet cell

C
Kupffer's cell

D
Acinar cell

Solution

The pancreatic acinar cell is the functional unit of the exocrine pancreas. It synthesizes, stores, and secretes digestive enzymes. Under normal physiological conditions, digestive enzymes are activated only once they have reached the duodenum.
Question 9
1 / -0

Pepsinogen is secreted by

A
Chief cells

B
Oxyntic cells

C
Mast cells

D
Parietal cells

Solution

Gastric chief cell (also known as a zymogenic cell or peptic cell) is a cell in the stomach, that releases pepsinogen and chymosin. Pepsinogen is activated into the digestive enzyme pepsin, when it comes in contact with acid produced by gastric parietal cells.
Question 10
1 / -0

What will happen if the secretion of parietal cells of gastric glands is blocked with an inhibitor?

A
In the absence of HCl secretion inactive pepsinogen is not converted into the active enzyme pepsin.

B
Enterokinase will not be released from the duodenal mucosa and so trypsinogen is not converted to trypsin.

C
Gastric juice will be deficient in chymosin.

D
Gastric juice will be deficient in pepsinogen.
Solution
Correct Option: A
Explanation:
Parietal cells of the gastric glands are located in the fundus-body region.
they secrete hydrochloric acid.
this hydrochloric acid is required to create an acidic environment in the stomach.
in presence of HCL, inactive pepsinogen is converted into active enzyme pepsin. .
this pepsin will further be involved in some other conversation.
Hence, if parietal cells of gastric glands are blocked with an inhibitor, it will not be able to secrete HCL, and inactive pepsinogen will not convert into the active enzyme pepsin.
