|---|---|---|---|
| (a) | Furacin | (i) | Antibiotic |
| (b) | Arsphenamine | (ii) | Tranquilizers |
| (c) | Dimetone | (iii) | Antiseptic |
| (d) | Valium | (iv) | Synthetic antihistamines Choose the most appropriate match : |
furacine acts as Antiseptic Arsphenamine also known as salvarsan acts as antibiotic Dimetone is synthetic histamine valium is a Tranquilizer
Histamine – does not contain sulphur.
Antihistamines not affect the secretion of acid in stomach, the reason is that antiallergic and antacid drugs work on different receptors.
1. Ranitidine : Antacid 2. Meprobamate : Tranquilizer 3. Terfenadine : Antihistamine 4. Brompheniramine : Antihistamine
Equanil is for depression and hypertension.
Statement (A) is incorrect.
Antibiotics are substances that are produced by microorganisms to inhibit the growth of other microorganisms.
Antibiotics are not meant to promote the growth or survival of microorganisms, but rather to control or eliminate them.
Seliwanoff test and Xanthaproteic test are used for identification of 'Ketoses' and proteins respectively.
Statement I: Noradrenaline is a neurotransmitter.
This statement is correct.
Noradrenaline is a type of neurotransmitter, which are chemicals that help transmit signals from one nerve cell to another.
Noradrenaline is produced and released by nerve cells and acts on other nerve cells, as well as on various organs and tissues in the body, to regulate important functions such as heart rate, blood pressure, and alertness.
Statement II: Low level of noradrenaline is not the cause of depression in human.
This statement is incorrect.
Although depression can be caused by a variety of factors, low levels of noradrenaline have been linked to depression in some cases.
Studies have shown that individuals with depression often have reduced levels of noradrenaline in certain areas of the brain, leading researchers to believe that a deficiency in this neurotransmitter may contribute to depression.
However, it is important to note that depression is a complex disorder with multiple causes, and low levels of noradrenaline may not be the sole cause of depression in all individuals.
The correct answer is Option B: alkaline hydrolysis reaction.
Saponification is the alkaline hydrolysis of an ester into its component fatty acids and alcohol.
In the context of soapmaking, this reaction is used to convert animal fats or vegetable oils into soap and glycerin.
The reaction is catalyzed by a strong base, such as sodium hydroxide or potassium hydroxide.
The base reacts with the ester group in the fat or oil, breaking it down into its component fatty acids and alcohol.
The fatty acids then react with the base to form soap molecules.
The soap molecules have a long, hydrophobic (water-hating) tail and a short, hydrophilic (water-loving) head.
The hydrophobic tail dissolves in oil, while the hydrophilic head dissolves in water.
This allows soap to act as an emulsifying agent, which means it can help to mix oil and water together.
Soap is also a surfactant, which means it lowers the surface tension of water.
This makes it easier for water to wet surfaces and remove dirt and grime.
Saponification is a versatile reaction that has many applications beyond soapmaking.
It is also used to make biodiesel fuel, detergents, and other products.
Antagonists are substances that interfere with or inhibit the physiological action of another.
They bind to receptors but do not activate them, and instead block the receptors from being activated by other substances.
Statement A is true.
Antagonists do bind to the receptor site, blocking it from being activated by other substances.
Statement B is not typically true.
Antagonists work by binding to the receptor site on the cell surface, not by being transferred inside the cell.
Statement C is true.
By blocking the receptor site, antagonists can inhibit the natural communication of the body.
Statement D is not true.
Antagonists do not mimic the natural messenger.
They block its action instead.
This is in contrast to agonists, which do mimic the action of the natural messenger.
Therefore, Option C "A and C" is the correct answer.
