Weekly Quiz Competition

Question 1
4 / -1

Pancreatic juice rich in water and electrolytes but poor in enzymes is secreted in response to

A
Pancreozymin

B
Cholecystokinin

C
Secretin

D
Hepatoinin

Solution

Secretin enzyme stimulates the acinar cells of pancreas to secrete water and bicarbonate in pancreatic ducts that drain into the duodenum.
Question 2
4 / -1

Total gastrectomy may lead to

A
Haemolytic anaemia

B
Pernicious anaemia

C
Diarrhoea

D
Indigenstion

Solution

Iron deficiency anemia develops because removal of the stomach often leads to a marked decrease in the production of gastric acid.
Question 3
4 / -1

If the bile-pancreatic duct is blocked, the following will NOT be affected

A
Digestion of proteins

B
Emulsification of fats

C
Level of blood glucose

D
Digestion of starch

Solution

Level of blood glucose, because it's controlled by INSULIN hormone and it's released into blood vessels or near tissue and bile-pancreatic duct is not affected insulin level.
Question 4
4 / -1

An adult person consumers boiled potato. Mark the correct statement regarding the digestion of food components

A
Cellulose will be digested

B
Starch will not be digested

C
Lactase will digest carbohydrates

D
DNA will be digested by pancreatic enzymes

Solution

Cellulose can't be digested in human body.Starch will be digested. Lactase has no effect on carbohydrates.So , the last option is correct. DNA of the potato will be digested by DNAse enzyme
Question 5
4 / -1

Humans can synthesis following vitamins

A
B12

B
Folic acid

C
Vitamin A and D

D
All of these

Solution

Humans can produce some vitamins from precursors they consume: for example, vitamin A is synthesized from beta carotene; and niacin is synthesized from the amino acid tryptophan.

When exposed to the sun, your skin can manufacture its own vitamin D.
Question 6
4 / -1

The chloride content of RBC will be higher than that of plasma in

A
Systemic arteries and pulmonary veins

B
Systemic veins and pulmonary arteries

C
Systemic and pulmonary arteries

D
Systemic and pulmonary veins

Solution

While RBC is in systemic veins and pulmonary arteries, carrying some amount of CO₂, the chloride ion is present in the RBC as a result of Haldane's effect/ Chloride shift effect. Hence, in systemic veins and pulmonary arteries the RBC have higher chloride ion concentration
Question 7
4 / -1

Byssinosis is an occupational lung disease which may occur in

A
Cement factory workers

B
Cotton mill workers

C
Sugar mill workers

D
Coal mines

Solution

Byssinosis is an occupational lung disease that primarily affects workers in cotton processing, hemp or flax industries. Other names for byssinosis include Monday fever, brown lung disease, mill fever or cotton workers' lung.
Question 8
4 / -1

If the volume of CO₂ liberated during respiration is more than the volume of O₂ used, the respiratory substrate will be

A
Fat

B
Organic acid

C
Protein

D
Carbohydrate

Solution

This is because a respiratory quotient (RQ) for Organic acids is more than one. fats and proteins have RQ less than 1. While carbohydrate have RQ = 1

RQ = (volume of CO₂ evolved)÷(volume of O₂ required)
Question 9
4 / -1

Deoxyhemoglobin binds with more H than oxyhaemoglobin does. It is described by

A
Bohr’s effect

B
Hering-Breuer reflex

C
Haldane’s effect

D
Hamburger’s effect

Solution

In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).
Question 10
4 / -1

If the oxyhaemoglobin dissociation curves of maternal and foetal haemoglobin are compared, the foetal curve will be on

A
Right hand side and sigmoid

B
Left hand side and sigmoid

C
Right hand side and parabola

D
Left hand side and parabola

Solution

As you know that efficiency of foetal RBC will be more then adults. So even at low pO2 (as compared to adults) %age of saturation will be high. So graph will move to left and sigmoid
