Which of the following is not a tranquilizer?

A
Luminal

B
Seconal

C
Valium

D
Alitame

Solution

$$Alitame$$ is an artificial sweetener developed in the early 1980s and currently marketed in some countries under the brand name Aclame.
Luminal, seconal and valium are tranquilizers.
Question 5
1 / -0

Which of the following is used as an antacid?

A
ampicillin

B
omeprazole

C
lansoprazole

D
both b and c

Solution

Ampicillin is a beta-lactam antibiotic that is part of the aminopenicillin family.
Lansoprazole and Omeprazole are proton-pump inhibitor (PPI), which inhibit the stomach's production of gastric acids, hence acting as antacids.
Hence, option D is correct.
Question 6
1 / -0

$$2-acetoxy$$ benzoic acid is:

A
antiseptic

B
aspirin

C
antibiotic

D
mordant dye

Aspirin is $$2-acetoxybenzoic$$ acid, also known as acetylsalicylic acid.
Question 7
1 / -0

Drugs can inhibit the catalytic activity of enzymes by binding at

A
active sites

B
allosteric sites

C
both active sites and allosteric sites

D
core of an enzyme

Solution

An enzyme inhibitor is a molecule, which binds to enzymes and decreases their activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. Drugs can attack both the active as well as the allosteric sites of an enzyme by binding to these sites and decreasing the catalytic activity of the enzymes.
Question 8
1 / -0

Which of the following represents analgesics?

A
Equanil

B
Quinine

C
Novalgin

D
Penicillin

Solution

Question 9
1 / -0

What is the source of receptor proteins?

A
Interior of a cell

B
Cell wall

C
Out of cell wall

D
Fixed in the cell membrane partially inside and partially projected outward

Solution

The source of receptor proteins is fixed in the cell wall, partly inside and partly projected out of the cell wall.
This is so that chemical messengers can interact with the outside portion of receptor protein, which transfers the signal to interior of cell via the receptor protein.
Hence, signal is transferred from outside the cell to inside without the messenger having to cross the cell membrane.
Question 10
1 / -0

Which of the following is 100 times sweeter than sugar?

A
Sucrolose

B
Saccharin

C
Aspartame

D
Alitame

Solution

Aspartame is an artificial, non-saccharide sweetener used as a sugar substitute in some foods and beverages.
In the European Union, it is codified as E951. Aspartame is a methyl ester of the aspartic acid/phenylalanine dipeptide. It is almost 100 times sweeter than sugar.
Hence, option C is correct.
