21
Which is a protein-splitting enzyme?
RRB Group-D
23/08/2022 / Shift I
2022
✓ Answer:DPepsin
Pepsin is a protease that breaks peptide bonds in proteins.
22
The thousands of finger-like outgrowths on the inner wall of the small intestine are called:
Villi are projections of the intestinal lining that increase absorptive surface area.
23
Which digestive process is similar to soap emulsifying greasy dirt?
RRB Group-D
17/08/2022 / Shift II
2022
✓ Answer:ABile salts splitting large fat globules into smaller droplets
Bile salts emulsify fat into small droplets, increasing the surface area for lipase action.
24
Where are villi found in the body?
RRB NTPC (Stage-I)
09/02/2021 / Shift I
2021
✓ Answer:ASmall intestine
The small intestine contains villi specialized for nutrient absorption.
25
Match the labelled organs in the source diagram: a = oesophagus, b = large intestine, c = small intestine, d = liver. Functions: i. Villi absorb water from food; ii. Length depends on the food an organism eats; iii. Helps emulsify fats; iv. No digestion. Select the matching option.
RRB Group-D
30/08/2022 / Shift I
2022
✓ Answer:Da-iv, b-i, c-ii, d-iii
Source key: D. The source statement i is flawed: the large intestine absorbs water but does not have villi. Villi occur in the small intestine. The organ labels are transcribed from the diagram, and the original matching choices are retained.
26
What are the finger-like projections that increase the small intestine's area for absorption called?
RRB Group-D
13/09/2022 / Shift II
2022
✓ Answer:DVilli
Villi enlarge the intestinal surface available for absorption.
27
What is the site of complete digestion of carbohydrates, proteins and fats?
RRB Group-D
17/09/2022 / Shift III
2022
✓ Answer:BSmall intestine
Pancreatic and intestinal enzymes complete digestion of these nutrients in the small intestine.
28
In which part of the human body are villi present?
RRB Group-D
28/09/2022 / Shift III
2022
✓ Answer:BSmall intestine
Villi line the small intestine and aid absorption.
29
Complete digestion of carbohydrates, proteins and fats takes place in the:
RRB ALP & Technician
29/08/2018 / Shift I
2018
✓ Answer:CSmall intestine
The small intestine receives pancreatic enzymes and bile and completes nutrient digestion.
30
What is the function of gustatory receptors?
RRB Technicians Grade-III
24/12/2024 / Shift III
2024
✓ Answer:BDetect taste
Gustatory receptors respond to dissolved substances and produce the sensation of taste.
