  • Oral cavity

  • Pharynx

  • More than one option is correct

Bolus from oral cavity to ……... Oesophagus……..stomach. Which of the process/ movements are responsible for it?

  • Deglutition and segmentation

  • Deglutition and peristalsis

  • Peristalsis and segmentation

  • Peristalsis and deglutition

Saliva does not has

  • Lysozyme

  • Carbohydrate splitting enzyme

  • Protease

  • Chloride ions

Which of the following statement is not wrong about carbohydrate digestion?

  • 30% of carbohydrate digestion occurs in mouth

  • 30% of starch hydrolysis occurs in mouth

  • 70% carbohydrate digestion occurs in small intestine.

  • More than one options are correct.

Intrinsic factor is secreted by

  • Parietal cells/ chief cells

  • Oxyntic/peptic cells

  • Oxyntic / parietal cells

  • Chief/ peptic cells

Which of the following is major product of chief cells?

  • Pepsinogen

  • Mucus

  • HCl

  • Vitamin B12

Find the wrong one.

  • Churning movement- stomach

  • Chyme- stomach

  • Bolus- Mouth

  • Stomach- storage of food for 2 to 3 hrs

Pepsin is

  • Proteolytic enzyme

  • Activated by HCl

  • Converts proteins into peptones and peptides

  • More than one option is correct.

HCl of stomach can damage mucosal epithelia of stomach but

  • Mucus prevents it

  • Mucus along with carbonate prevent it.

  • Mucus+bicarbonate prevent it

  • Only bicarbonate prevents it.

Which of the following is correct?

  • Milk fats are digested by Rennin.

  • A prolytic enzyme found in infants.

  • Rennin is active at pH-1.8

  • Lingual lipases are not present in gastric juice

Various types of movements are generated in…...layer of …..

  • Muscularis, gall bladder 

  • Mucosal, small intestine

  • Muscularis, small intestine

  • Mucosal, stomach

The intestinal juice secretes

  • Dipeptidase

  • Bile

  • Procarboxypeptidase

  • Trypsinogen

Pancreatic nucleases are activated by-

  • Enterokinase

  • Trypsinogen

  • Trypsin

  • Enteropeptide

Which of the following is not a component of bile?

  • Bilirubin

  • Phospholipids

  • Enzyme

  • Cholesterol

Gastric lipase do not work because

  • Lipases are very less in amount

  • No bile is there to activate lipase

  • Fats are inaccessible in stomach because of rugae

  • Lipases act in the presence of trypsin, a pancreatic enzyme.

Succus entericus is

  • Secretion of goblet cells+ secretion of mucosal brush border cells of intestine

  • Secretion of intestinal goblet cells

  • Secretion of brush border intestinal cells

  • Secretion of pancreatic exocrine portion

Which of the following is not an enzyme of intestine?

  • Dipeptidase

  • Amylases

  • Nucleosidases

  • None of these

Protection of intestinal Mucosa from HCl is carried out by-

  • Alkaline secretion of pancreas

  • Sub-mucosal glands of duodenum

  • Mucus from intestinal goblet cells

  • All of these

Proteolytic enzyme of pancreas is not

  • Trypsin

  • Chymotrypsin

  • Carboxypeptidase

  • Protopeptidase

Carbohydrates in the chyme are hydrolysed by pancreatic amylase and results into

  • Disaccharides

  • Maltose

  • Lactose

  • Sucrose

The succus entericus does not act on

  • Dipeptides

  • Nucleotides

  • Nucleosides

  • Peptones

Final steps of digestion occur -

  • Occurs very close to mucosal epithelium of intestine

  • Occurs in lumen of intestine

  • Occurs inside mucosal epithelia of intestine

  • Occurs in the rugae if intestine

Nucleosides are acted upon by nucleosidases and give rise to

  • Sugars and bases

  • Sugars, bases and phosphates

  • Sugars and phosphates

  • Bases and phosphates
