Weekly Quiz Competition

Question 1
1 / -0

A person suffering from depression is administered

A
Iproniazid

B
Phenacetin

C
Ibuprofen

D
Paracetamol

Solution

Antidepressant drugs inhibit the enzymes which catalyse the degradation of noradrenaline. If the enzyme is inhibited, this important neurotransmitter is slowly metabolised and can activate its receptor for longer periods of time, thus counteracting the effect of depression. Iproniazid and phenelzine are two such drugs.
Question 2
1 / -0

A sample of water was found to contain Ca²⁺ ions. Which of these will be preferred for washing clothes?

A
Bleach

B
Detergents

C
Soaps

D
Liquid soaps

Solution

Ca²⁺ ions present makes the water hard by forming insoluble calcium soaps when sodium or potassium soaps are dissolved in hard water. Synthetic detergents are cleansing agents which have all the properties of soaps, but which actually do not contain any soap. These can be used both in soft and hard water as they give foam even in hard water.
Question 3
1 / -0

The disadvantage of using Penicillin is

A
Can’t effectively kill the microbes

B
Causes allergic reactions

C
Not easily metabolized by the body

D
Not easily available

Solution

Pencillin causes allergic reactions. So, it is absolutely essential to test the patients for sensitivity (allergy) to penicillin before it is administered.
Question 4
1 / -0

A soap helps to reduce body odour due to bacterial decomposition because it contains

A
Antiseptic

B
Perfume

C
Antibiotic

D
Antioxidants

Solution

An antiseptic bithionol (also called bithional) is added to soaps to impart antiseptic properties.
Question 5
1 / -0

Sodium carbonate added to soap acts as a

A
builder

B
foaming agent

C
filler

D
scouring agent

Solution

Builders like sodium carbonate and trisodium phosphate make the soaps act more rapidly.
Question 6
1 / -0

The effective medicine to be given to a person suffering from hyperacidity is

A
Seldane

B
Cimetidine

C
Anacin

D
Valium

Solution

The drug cimetidine(Tegamet), was designed to prevent the interaction of histamine with the receptors present in the stomach wall. This resulted in release of lesser amount of acid.
Question 7
1 / -0

The purpose of adding bithional to medicated soaps is

A
To impart antiseptic properties

B
To make it look attractive

C
To give a good smell

D
To prevent soap from drying

Solution

Biithionol (also called bithional) is added to soaps to impart antiseptic properties.
Question 8
1 / -0

Scum formation can be prevented by

A
using water softeners

B
using soft water

C
using detergents

D
All of these

Solution

Hard water contains calcium and magnesium ions. These ions form insoluble calcium and magnesium soaps respectively when sodium or potassium soaps are dissolved in hard water. It can be avoided by using soft water or by adding water softeners to hard water or by using detergents which don't form insoluble precipitate in even hard water.
Question 9
1 / -0

Alkyl benzenesulphonate, an anionic detergent is widely used in

A
Liquid dish – washing detergents

B
Household detergents

C
Germicides

D
Hand sanitizer

Solution

Anionic detergents are sodium salts of sulphonated long chain alcohol or hydrocarbons. In anionic detergents, the anionic part of the molecule is involved in the cleansing action. They are mostly used for household work.
Question 10
1 / -0

Different receptors in our body show selectivity for one chemical messenger over the other because

A
different shape of binding site

B
different amino acid composition of the binding site

C
different structure of binding sites

D
All of these

Solution

There are a large number of different receptors in the body that interact with different chemical messengers. These receptors show selectivity for one chemical messenger over the other because their binding sites have different shape, structure and amino acid composition.
