What normally protects the stomach lining from acid?
RRB NTPC (Stage-I)
05/01/2021 / Shift I
2021
✓ Answer:AMucus
The mucus-bicarbonate barrier protects the gastric lining from acid and digestive enzymes.
92
Where does most fat digestion occur?
RRB NTPC (Stage-I)
03/04/2021 / Shift II
2021
✓ Answer:CSmall intestine
Most fat digestion occurs in the small intestine through pancreatic lipase, aided by bile salts.
93
Which statement is NOT correct?
RRB NTPC (Stage-I)
06/04/2021 / Shift I
2021
✓ Answer:AThe stomach receives secretions from the liver and pancreas
Bile and pancreatic juice enter the duodenum of the small intestine, not the stomach. Pepsin is secreted initially as pepsinogen.
94
The pancreas is part of which system among these options?
RRB NTPC (Stage-I)
31/03/2016 / Shift I
2016
✓ Answer:CDigestive system
The pancreas secretes digestive enzymes into the small intestine. It also has endocrine functions.
95
Which is not part of the human alimentary canal?
RRB Group-D
23/10/2018 / Shift III
2018
✓ Answer:BAlveoli
Source key: B. Alveoli belong to the lungs. However, the gallbladder is an accessory digestive organ and also is not part of the alimentary canal itself, making the printed question ambiguous.
96
Coliform bacteria in drinking water can indicate:
RRB NTPC (Stage-I)
30/04/2016 / Shift III
2016
✓ Answer:DContamination from human waste
Source key: D. Faecal coliforms, particularly E. coli, indicate possible faecal contamination. Total coliforms alone are not specific to human waste.
97
In which unit is energy obtained from food commonly measured?
RRB NTPC (Stage-I)
18/04/2016 / Shift I
2016
✓ Answer:ACalories
Food energy is commonly expressed in kilocalories, also called dietary Calories, and in kilojoules.
98
Saliva contains which enzyme?
RRB Group-D
25/10/2018 / Shift II
2018
✓ Answer:CAmylase
The intended answer is salivary amylase, which initiates starch digestion.
99
Metabolism is related to: I. All chemical reactions in the body. II. Synthesis of complex molecules from simple molecules. III. Anabolism and catabolism.
RRB NTPC (Stage-I)
29/04/2016 / Shift III
2016
✓ Answer:DI, II and III
Metabolism includes all biochemical reactions, both synthesis through anabolism and breakdown through catabolism.
100
Which of these organs has a notable capacity to regenerate?
RRB NTPC (Stage-I)
29/03/2016 / Shift I
2016
✓ Answer:CLiver
The liver can restore much of its mass after partial loss. The source's wording that it is the only body part capable of regeneration is an overstatement.
