Which ONE of the following molecules is a secondary metabolite?
1 Ethanol
2 Lactate
3 Penicillin
4 Citric Acid
Explanation:
Exp: C Penicillin is secondary metabolites. Secondary metabolites are the natural organic products of low molecular mass produced by bacteria, fungi, animals or plants which are not directly involved in the normal growth, development or reproduction of the organism. Their production is influenced by environmental factors and production is regulated by complex - biochemical pathways.

Which of the following secondary metabolites belong to the group drugs? (i) Morphine (ii) Curcumin (iii) Codeine (iv) Vinblastine (v) Abrin
1 i and ii only
2 i and v only
3 ii and iii only
4 ii and iv only
5 iii and iv only
Explanation:
Exp: D Curcumin and vinblastine secondary metabolites belong to the group drugs. Vinblastine is used as an anticancer drug. It is the salt of an alkaloid extracted from of flowering herb commonly known as periwinkle. Curcumine is a component of turmeric and also used as a drug. It is produced by plaints of Curcuma longa species. It can help in oxidative, inflammatory conditions, metabolic syndrome, arthritis etc.

Three crops that contribute maximum to global food grain production are -
1 Wheat, rice and maize
2 Rice, maize and sorghum
3 Wheat maize and sorghum
4 Wheat, rice and barley
Explanation:
Exp: A Wheat, rice and maize contribute maximum to global food grain production. They are a rich source of carbohydrate, present in endosperm, which is edible portion in cereals. - Rice alone is the staple food of \(60 \%\) of world population more than \(50 \%\) Indians. - Wheat is world's most widely cultivated crop. Maize is an important Kharif crop of India and also contributed to food production.
