1 / -0

The difficulty in using Alitame as artificial sweetener is

A
It is not stable at high temperature

B
It adds calories

C
It is a high potency sweetener

D
It is metabolized in the body

Solution

Alitame is high potency sweetener, although it is more stable than aspartame, the control of sweetness of food is difficult while using it.
Question 2
1 / -0

Toilet soaps are prepared by

A
adding scouring agents

B
using better grades of fats and oils

C
adding fillers

D
adding a gum called rosin

Solution

Toilet soaps are prepared by using better grades of fats and oils and care is taken to remove excess alkali. Colour and perfumes are added to make these more attractive.
Question 3
1 / -0

Shaving soaps contain

A
sodium carbonate

B
borax

C
glycerol

D
sodium silicate

Solution

Shaving soaps contain glycerol to prevent rapid drying.
Question 4
1 / -0

A gum called, rosin is added while making

A
medicated soaps

B

C
shaving soaps

D

Solution

A gum called, rosin is added while making shaving soaps. It forms sodium rosinate which lathers well.
Question 5
1 / -0

Cimetidine and Ranitidine are better antacids mainly because

A
They restrict their action only to neutralizing the excess acid

B
They keep the pH of the stomach neutral

C
They remove both the symptoms and cause of acidity

D
They are easily synthesized

Solution

The drug cimetidine (Tegamet), was designed to prevent the interaction of histamine (stimulates the secretion of pepsin and hydrochloric acid in the stomach) with the receptors present in the stomach wall. This resulted in release of lesser amount of acid. Thus the given drugs remove acidity as well treat the symptoms.
Question 6
1 / -0

Antacids and Anti – allergic drugs do not interfere with each other because

A
Both are antihistamines but work on different receptors

B
Both react with the same receptor differently

C
Both are not antihistamines and work on the same receptors

D
Both are not antihistamines

Solution

Antacids prevent the interaction of histamine with the receptors present in the stomach wall. This results in release of lesser amount of acid. Anti-allergic drugs have antihistamines which interfere with the natural action of histamine by competing with histamine for binding sites of receptor where histamine exerts its effect. Thus antiallergic and antacid drugs work on different receptors.
Question 7
1 / -0

Tranquilizers act on

A
Central Nervous system

B
Circulatory system

C
Respiratory system

D
Excretory system

Solution

Tranquilizers are neurologically active drugs. These affect the message transfer mechanism from nerve to receptor. They work on central nervous system.
Question 8
1 / -0

Chloramphenicol is used to treat typhoid, dysentery, acute fever, meningitis etc., because it is

A
Bacteriostatic and broad spectrum antibiotic

B
Bactericidal and broad spectrum antibiotic

C
Bacteriostatic and narrow spectrum antibiotic

D
Bactericidal and narrow spectrum antibiotic

Solution

Chloramphenicol is a broad spectrum antibiotic and bacterostatic. It is rapidly absorbed from the gastrointestinal tract and hence can be given orally in case of typhoid, dysentery, acute fever, certain form of urinary infections, meningitis and pneumonia.
Question 9
1 / -0

A
Noradrenaline

B
Serotonin

C
Dopamine

Solution

Noradrenaline is one of the neurotransmitters which play role in mood swings. If the level of noradrenaline is low for some reason, then the signal-sending activity becomes low, and the person suffers from depression.
Question 10
1 / -0

Lather formed in shaving soaps is due to

A
Sodium silicate

B
Borax

C
Glycerol

D
Sodium rosinate

Solution

Shaving soaps contain glycerol to prevent rapid drying. A gum called, rosin is added while making them. It forms sodium rosinate which lathers well. So lather forms in shaving soaps is due to Sodium rosinate.
