    Correct Answer
    A. Quinine
    Explanation
    Quinine is the correct answer because it is the principal cinchona alkaloid used as an anti-protozoal drug. Cinchona alkaloids are derived from the bark of the cinchona tree and have been used for centuries to treat malaria. Quinine specifically has been proven effective in treating malaria caused by Plasmodium falciparum, the most deadly species of the parasite. It works by interfering with the parasite's ability to break down hemoglobin, ultimately killing the parasite. Chloroquine, quinacrine, quinidine, and eserine salicylate are also anti-protozoal drugs, but they are not the principal cinchona alkaloid used therapeutically.

    Alkaloids as salts may be liberated from plant components using: 

    • Acidulated water

    • Sodium carbonate

    • Methanol

    • Ether

    Correct Answer
    A. Sodium carbonate
    Explanation
    Sodium carbonate can be used to liberate alkaloids from plant components. This is because sodium carbonate is a strong base and can react with acidic components in the plant, such as phenolic acids or tannins, to form water-soluble salts. These salts can then be easily extracted using water. Methanol and ether are organic solvents that can be used for extraction, but they do not have the ability to liberate alkaloids from plant components. Acidulated water, on the other hand, would not be suitable for this purpose as it would not help in liberating alkaloids.

    Explanation
    Myrrh is an aromatic resin that was commonly used by the ancient Egyptians in the embalming process. It was one of the ingredients in their embalming material, which was used to preserve the bodies of the deceased. Myrrh has antimicrobial properties and a strong fragrance, making it an ideal ingredient for embalming. It was also used in religious rituals and as a perfume in ancient Egypt. Therefore, myrrh is the correct answer as it is directly associated with the embalming material used by the Egyptians.

    Attacks protopectin yielding soluble pectin:

    • Protopectinase

    • Pectose

    • Pectinase

    • Pectase

    Correct Answer
    A. Protopectinase
    Explanation
    Protopectase is the correct answer because it is an enzyme that attacks protopectin, breaking it down into soluble pectin. Protopectin is a complex carbohydrate found in plant cell walls that can be converted into pectin through enzymatic action. Pectinase and pectase are enzymes that also act on pectin, but they do not specifically target protopectin. Pectose, on the other hand, is a product of the breakdown of pectin, not an enzyme that breaks down protopectin.
