  1. In the head

  2. In the left side of the body

  3. In the right side of the body

  4. Below the abdomen

Show answer
Correct Option: B
Explanation:
  • The stomach is a muscular organ located on the left side of the upper abdomen. 
  • The stomach receives food from the oesophagus.
  •  As food reaches the end of the oesophagus, it enters the stomach through a muscular valve called the lower oesophagal sphincter.
  •  The stomach secretes acid and enzymes that digest food. Hence, our stomach is located on the left side of the body.
So, the correct answer is 'on the left side of the body'.

Which part of the digestive system secretes peritrophic membrane around the food in cockroach?

evs food trends types of ecological pyramids the muscular system and digestive system in human beings introduction to human digestive system

  1. Crop

  2. Gizzard

  3. Hepatic caecae

  4. Mesenteron

Show answer
Correct Option: C
Explanation:

Answer C: Hepatic Caecae

The digestive juices flow into the stomach owing to the caecae secretion. The midgut is lined by a peritrophic membrane and not by a cuticle or cuticle.

The archenteron develops into

  1. blastocoel

  2. endoderm

  3. lumen of the digestive tract

  4. placenta

Show answer
Correct Option: C
Explanation:

Archenteron is the primary cavity which is formed at the initial stage of gastrulation. This cavity begins at the dorsal lip of blastopore which is at the one side of the dividing zygote and then this cavity moves through the zygote to the other side which gives rise to the anus. 

So the correct option is 'lumen of digestive tract

How many of the enzymes given below in block belong to brush border enzymes?
Multase, Nucleosidase, Enterokinase, Amylopsin, Steapsin, Nucleases, Erepsin, Carboxypeptidase, Lactase, Aminopeptidase

evs food trends types of ecological pyramids the muscular system and digestive system in human beings introduction to human digestive system

  1. Six

  2. Seven

  3. Five

  4. Four

Show answer
Correct Option: D
Explanation:

The brush borders of the intestinal lining are the site of terminal carbohydrate digestions. The microvilli that constitute the brush border have enzymes for this final part of digestion anchored into their apical plasma membrane as integral membrane proteins. Maltase, lactase, erepsin, nucleosidase are the brush border enzymes.

So, the correct option is 'four'.

Citrate undergoes dehydration to form unstable compound

evs food trends types of ecological pyramids the muscular system and digestive system in human beings introduction to human digestive system

  1. iso-citrate

  2. succinate

  3. cis-aconitate

  4. aconitate

Show answer
Correct Option: A
Explanation:

In step two, an enzyme called aconitase converts citrate into isocitrate. Next, an isocitrate dehydrogenase enzyme oxidizes isocitrate, a six-carbon molecule, to a five-carbon α-ketoglutarate. The carbon that was lost is released as carbon dioxide and one NADH is also formed.

So, the correct option is, 'Isocitrate'.

Which reserve food is consumed by man during starvation:

  1. Fat

  2. Protein

  3. Glycogen

  4. Vitamin

Show answer
Correct Option: A
Explanation:

Starvation is defined as a severe deficiency in calorie energy intake needed to maintain human life.

During first stage of starvation, glucose levels are maintained through production of glucose from proteins, glycogen and fats.Then body burns fats first exhusting contents of digestive tract along with glycogen resetrves stored in liver cells.

Which of the following break down the food into the simpler form that the body can use?

  1. Digestive juice

  2. Teeth

  3. Water

  4. None of the above

Show answer
Correct Option: A
Explanation:

The digestive juices consist of saliva, gastric juice, pancreatic juice, intestinal juice and bile. They help in break down of complex food into simpler building block components that can easily be absorbed by the body. These reactions occur outside the cells lining the gut.

So the correct answer is 'Digestive juice'.

Most digestion and all absorption of food take place in the :-

  1. small intestine

  2. large intestine

  3. stomach

  4. caecum

Show answer
Correct Option: A
Explanation:

Pepsin is the chief digestive enzyme in the stomach that stomach that breaks down proteins. Cells produce pepsinogen that is produced to act on mucus by epithelial cells of the stomach that helps to protect the lining of the stomach from corrosive hydrochloric acid and pepsin. And the absorption is done in small intestine.

So, the correct option is 'small intestine'.
