Question 1
1 / -0

The final products of digestion should be

A
Fat soluble and should be able to pass through cell walls.

B
Water soluble and should be able to pass through cell walls.

C
Fat soluble and should be able to pass through cell membranes.

D
Water soluble and should be able to pass through cell membranes.
Solution
- Digestion is catabolic process in the digestive tract where ingested food is converted into simpler, soluble and diffusible substances that can be assimilated by the body and absorbed into the blood from the intestinal walls.
- The end product should be water soluble as it has to combine with the plasma of blood.
- Absorption at intestinal walls is through cell membranes of intestinal cells and walls of blood capillaries.
- So, the correct answer is 'Water soluble and should be able to pass through cell membranes'.
Question 2
1 / -0

The opening of the stomach in duodenum is regulated by

A
Sphineter of Oddi

B
Pyloric sphincter

C
Gastro-oesophageal

D
Ileo-caeeal valve

Solution

A. Sphincter of Oddi is the opening of the hepatopancreatic duct into duodenum.
B. Pyloric sphincter is found between the duodenum and posterior stomach. It regulates the opening of duodenum into stomach.
C. Gastro-oesophageal sphincter is found between the oesophagus and stomach.
D. Ileo-caecal valve is present between ileum of small intestine and caecum of large intestine.
So, the correct answer is 'Pyloric sphincter'.
Question 3
1 / -0

Which of the following substance requires castle's intrinsic factor secreted by the stomach for absorption in the small intestine?

A
Amino acids

B
Water

C
Vitamin $$C$$

D
Vitamin $$B_{12}$$

Solution

Intrinsic factors which are released by the stomach are used in the ileum of the small intestine for the absorption of vitamin $$B_{12}$$. These are majorly made up of glycoproteins.
So the correct answer is option D.
Question 4
1 / -0

Innermost layer of mucosa is made up of columnar epithelium except :-

A
Oesophagus

B
Duodenum

C
Intestine

D
Stomach
Solution
- The mucosa (also known as mucous membrane) is the innermost layer of tissue. It’s a moist epithelial membrane that lines the alimentary canal lumen from mouth to the anus.
- Digestive mucosa is made up of three sublayers and the Innermost layer of the mucosa is made up of columnar epithelium except in the mouth, esophagus, and anus where it’s stratified squamous.
- Hence the Innermost layer of the mucosa is made up of columnar epithelium except for Oesopjhagus.
- So, the correct answer is 'Oesophagus'.
Question 5
1 / -0

The following are the symptoms of Kwashiorkor and marasmus. Categorize them correctly:-
I. It is caused by the deficiency of protein in the diet.
II. It is caused by the prolonged deficiency of protein and calories in the diet.
III. It affects infants under one year of age
IV It commonly affects babies between 1-3 years of age.
V. Subcutaneous fat persists.
VI. Subcutaneous fat is used up, making ribs very prominent.
VII. Skin and hair change colour.
VIII. May caused due to lack of protein in mother milk.
IX. No edema occurs.
X. No change in skin and hair colour.

A
Kwashiorkor - I, IV,V,VII, VIII. Marasmus - II, III,VI, IX,X

B
Kwashiorkor - I,II,V,VI,VIII, IX. Marasmus - III. IV, VII, X

C
Kwashiorkor - II,III,VI, IX, X. Marasmus - I, IV, V, VI, VIII

D
Kwashiorkor - III, IV, VII, X. Marasmus - I, II, V, VI, VIII, IX
Solution
- Kwashiorkor, also known as “edematous malnutrition” because of its association with edema (fluid retention), is a nutritional disorder most often seen in regions experiencing famine. It is a form of malnutrition caused by a lack of protein in the diet. People who have kwashiorkor typically have an extremely emaciated appearance in all body parts except their ankles, feet, and belly, which swell with fluid. Kwashiorkor is most common in countries where there is a limited supply or lack of food. It is mostly found in children and infants in sub-Saharan Africa, Southeast Asia, and Central America. Its symptoms include (1) change in skin and hair colour (to a rust colour) and texture (2) edema (swelling) of the ankles, feet, and belly.
- Marasmus is a severe form of protein-energy malnutrition that results when a person does not consume enough protein and calories. Without these vital nutrients, energy levels become dangerously low and vital functions begin to stop. Both adults and children can have marasmus, but it most often affects young children in developing countries. Over time, a person with marasmus will lose body tissue and fat in their face. Similarly, their bones become visible under their skin, and folds of skin develop from the loss of body mass. Their eyes may appear sunken.
So, the correct answer is 'Kwashiorkor - I, IV V VII, VIII. Marasmus - II. III. VI, IX,X'.
Question 6
1 / -0

Part of alimentary canal meant for reabsorption of water from chyle is

A
Small intestine

B
Colon

C
Large intestine

D
Rectum

Solution

The small intestine is meant for the reabsorption of water. Major absorption of water takes place in the intestine and further in the large intestine.
So, the correct option is 'small intestine'.
Question 7
1 / -0

Tongue is made up of?

A
Smooth muscles

B
Skeletal muscles

C
Both (A) and (B)

D
Cartilage

Solution

Answer :
i) The tongue is composed of skeletal muscle fibers and smooth muscle fibers.
ii) Unlike the cardiac muscle or smooth muscle of the organs and digestive system, skeletal muscle can be willingly controlled.
iii) This allows for the tongue's mobility.
iv) The muscles that lace throughout the organ secure it to surrounding bones and create the floor of the oral cavity.
v) Mucous membrane covers the skeletal muscle and protects the body from microbes and pathogens.
vi) While muscularis mucosa is composed of a layer of smooth muscle fibers.

So the correct answer is option C. Both (A) and (B).
Question 8
1 / -0

Calcium absorption is always enhanced by the action of the following vitamin

A
Vitamin A

B
Vitamin B

C
Vitamin D

D
Vitamin K

Solution

Vitamin D helps in the absorption of calcium ion from the walls of the duodenum to the bloodstream and also maintains its level in the body.
So the correct option is 'Vitamin D'.
Question 9
1 / -0

In rabbit, the digestion of cellulose takes place in

A
Colon

B
Ileum

C
Caecum

D
Rectum

Solution

The cecum is a blind sac or pouch, that is present at the junction of the small and large intestines. The food material that can be broken down further, mainly soluble fiber and proteins, moves into the cecum. The cecum has 10 times the capacity of the stomach of the rabbit. Here massive quantities of bacteria and microorganisms reside. The bacteria turn the indigestible fiber into digestible nutrients which are directly absorbed across the wall of the cecum for use by the animal, while others are excreted.
Question 10
1 / -0

Digestive enzymes are

A
Hydrolase

B
Oxido-reductase

C
Transferase

D
None of the above

Solution

Hydrolases are a class of more than 200 enzymes that catalyze the hydrolysis of several types of compounds. Esterases include lipases, which break ester bonds (between a carboxylic acid and an alcohol) in lipids. Nucleases, which are phosphatases hydrolyze nucleic acids. Glycosidases break bonds between sugar molecules in carbohydrates. Peptidases hydrolyze peptide bonds (between the carboxylic acid group of one amino acid and the amino group of another) within protein molecules. Digestion of macromolecules involves hydrolysis in which the anhydro bonds are broken down by the addition of water with the help of enzymes. These enzymes are called hydrolases.
