Which one of the following pairs is wrongly matched?
A
Textile – amylase
B
Detergents – lipase
C
Alcohol – nitrogenase
D
Fruit juice – pectinase
Detailed Solution
Amylases are used in the textile industry to remove starch (desizing) – correct.
Lipases are used in detergent formulations and help in removing oily stains from laundry – correct.
Pectinases (and proteases) are used to clarify bottled fruit juices – correct.
Alcohol is produced by the fermentation of sugars by yeast, through enzymes such as zymase; nitrogenase is the enzyme of nitrogen fixation and has nothing to do with alcohol production.
Hence the wrongly matched pair is alcohol – nitrogenase.
Lipases are used in detergent formulations and help in removing oily stains from laundry – correct.
Pectinases (and proteases) are used to clarify bottled fruit juices – correct.
Alcohol is produced by the fermentation of sugars by yeast, through enzymes such as zymase; nitrogenase is the enzyme of nitrogen fixation and has nothing to do with alcohol production.
Hence the wrongly matched pair is alcohol – nitrogenase.
