Biology GK Questions Quiz-73

1441.Fermentation is a type of ________ process . (1) Aerobic Respiration (2) Anaerobic Respiration (3) Exothermic Reaction (4) Transpiration Answer: 1441.(2) Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—under anaerobic conditions. It also occurs in oxygen-starved muscle cells, as in the case of lactic acid fermentation. 1442.Bacterial decomposition of biological material under anaerobic condition is (1) fermentation (2) fertilization (3) contamination (4) composting Answer: 1442.(1) Fermentation is the process by which complex organic compounds, such as glucose, are broken down by the action of enzymes into simpler compounds in the absence of oxygen (anaerobic). Yeasts can convert sugars to alcohol and carbon dioxide by fermentation. Fermentation is used to produce wine, beer, yogurt and other products. 1443.The elements known as primary nutrients for plants (1) Nitrogen, Phosphorus and Potassium (2) Ni…
