A
Iodoform

B
Dettol

C
Gammexane

D
Genatian violet

Solution

It is an insecticide.

A
Benzene

B
Benzoic acid

C
Phenol

D

Solution

Benzoic acid used as preservative as a Sodium Benzoate.
Question 4
1 / -0

A
Insulin

B
Penicilin

C
Chloroquine

D
Aspirin

Solution

Insulin is an antidiabatic drug.
Question 5
1 / -0

Which statement is false

A
Some disinfectants can be used antiseptics at low concentration

B
Sulphadiazine is a synthetic antibacterial

C
Ampicillin is a natural antibiotic

D
None of these

Solution

Ampicillin is a synthetic antibiotic.
Question 6
1 / -0

Which of the following substances is an antacid?

A
$$NaCl$$

B
$$Mg(OH)_{2}$$

C
$$HCl$$

D
$$H_{2}SO_{4}$$

Solution

B. $$Mg(OH)_{2}$$
An antacidis a basic substance which is taken for the remedy of acidity. $$Mg(OH)_{2}$$ also called milk of magnesia is a commonly used antacid.
Question 7
1 / -0

Assertion : Enzymes have active sites that hold substrate molecule for a chemical reaction
Reason : Drugs compete with natural substrate by attaching covalently to the active site of enzyme

A
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

B
Both Assertion and Reason are correct and Reason is NOT the correct explanation for Assertion

C
Both Assertion and Reason are incorrect

D
Assertion is correct but Reason is incorrect

E
Assertion is incorrect but Reason is correct

Solution

Option (B) is correct.
$$A$$ : Enzymes have active sites that hold substrate molecule for a chemical reaction. The substrate is held at the active site in a suitable and right position, for effective attack of reagent. This can be explained by lock and key model. The forces between the active site and substrate can be covalent bond, hydrogen bond, van der waal's forces etc.
$$R$$ : Drugs compete with natural substrate by attaching covalently to the active site of enzyme. Many drugs acts as enzyme inhibitors. Inhibition by particular chemicals can be a source of insight into the mechanism of enzyme action: specific inhibitors can often be used to identify residues critical for catalysis.
Question 8
1 / -0

Which one of the following is employed as a tranquilizer?

A
Naproxen

B
Tetracycline

C
Chlorpheniramine

D
Equanil

Solution

Equanil acts as a tranquilizer. Naproxen is analgesic, while tetracycline and chlorpheniramine are antibiotics.
Question 9
1 / -0

Assertion : Chemical messengers are chemicals that enable communication of message between two neurons or between neurons and muscles.
Reason : Chemicals enter the cell through receptor.

A
Both Assertion and Reason are incorrect.

B
Both Assertion and Reason are correct.

C
Both Assertion and Reason are correct and Reason is the incorrect explanation for Assertion.

D
Assertion is correct but Reason is incorrect.

E
non of these

Solution

Option (D) is correct. Assertion is correct but Reason is incorrect.
Chemical messengers are chemicals that enable communication of message between two neurons or between neurons and muscles.Chemical messages are transmitted to specific receptors through the extracellular fluids or across the synaptic gap.
These chemical messengers interact with receptors without entering the cell and change the shape of receptor and deliver the message.
Question 10
1 / -0

Veronal and luminal are derivatives of barbituric acid, which are:

A
tranquilizers

B
non-narcotic analgesic

C
antiallergic drugs

D
None of the above

Solution

Veronal and luminal are derivatives of barbituric acid which are tranquilizers and neurologically active drugs.

Tranquilizers are used to reduce anxiety, fear, tension, agitation, and related states of mental disturbance. Tranquilizers fall into two main classes, major and minor. Major tranquilizers, which are also known as antipsychotic agents, or neuroleptics, are so-called because they are used to treat major states of mental disturbance in schizophrenics and other psychotic patients.

Hence option A is correct.
