Bile is secreted by the:
RRB SSE
21/12/2014 / Set-08, Green Paper
2014
✓ Answer:BLiver
The liver produces bile; the gallbladder stores and releases it.
62
A diagram shows a food bolus moving down the oesophagus towards the stomach as the tube constricts behind it. Which process is occurring, and how?
RRB Group-D
30/09/2022 / Shift III
2022
✓ Answer:BPeristalsis through rhythmic contraction and relaxation of muscular walls
Peristaltic waves of muscle contraction and relaxation propel the bolus through the oesophagus. The source diagram is described in the question text.
63
Bile secretion in humans occurs in the:
RRB JE
14/12/2014 / Green Paper
2014
✓ Answer:DLiver
The liver secretes bile into the biliary system.
64
Match Group I with Group II. Group I: I. Mouth; II. Teeth; III. Tongue; IV. Saliva. Group II: A. Chewing food; B. Rolling food; C. Intake of whole food; D. Swallowing food.
RRB Group-D
26/09/2022 / Shift II
2022
✓ Answer:DI-C; II-A; III-B; IV-D
Food enters through the mouth, teeth chew it, the tongue rolls and shapes it, and saliva lubricates it to aid swallowing.
65
After complete digestion, proteins are converted into:
RRB NTPC (Stage-I)
29/01/2021 / Shift II
2021
✓ Answer:DAmino acids
Proteases and peptidases break proteins into amino acids, with digestion completed in the small intestine.
66
Which substance is used as an antacid for acidity-related indigestion?
RRB Group-D
26/09/2022 / Shift II
2022
✓ Answer:DMilk of magnesia
Milk of magnesia contains magnesium hydroxide, a base that neutralizes excess gastric acid.
67
What can humans NOT digest using their own digestive enzymes?
RRB NTPC (Stage-I)
29/01/2021 / Shift II
2021
✓ Answer:ACellulose
Humans do not produce cellulase, the enzyme needed to break down cellulose. Amino acids can be absorbed without further digestion.
68
According to the source, enzymes for the final conversion of proteins into amino acids, carbohydrates into glucose, and fats into fatty acids and glycerol are present in:
RRB Group-D
26/08/2022 / Shift I
2022
✓ Answer:BIntestinal juice
Source key: B. Intestinal enzymes complete peptide and carbohydrate digestion. This school-level description simplifies fat digestion, which depends mainly on pancreatic lipase in the small intestine.
69
Lactose intolerance is:
RRB NTPC (Stage-I)
15/02/2021 / Shift II
2021
✓ Answer:DAn inability to adequately break down the sugar found in dairy products
Insufficient lactase activity impairs digestion of lactose, the principal sugar in milk.
70
Which part of the alimentary canal carries out complete digestion of carbohydrates, proteins and fats?
RRB Group-D
09/09/2022 / Shift I
2022
✓ Answer:ASmall intestine
Digestion is completed mainly in the small intestine.
