Which one of the following pairs is wrongly matched?
Correct answer: A. Alcohol - Nitrogenase
- A. Alcohol - Nitrogenase
- B. Fruit juice - Pectinase
- C. Textile - Amylase
- D. Detergents - Lipase
Explanation
Yeast species are used in alcoholic fermentation due to the presence of the zymase enzyme. It was known that the yeast extract contained an enzyme zymase, which is nondialyzable, and a coenzyme that is dialyzable. It is now well known that zymase is a complex mixture of many enzymes and that several coenzymes are necessary for their function. The activity of this enzyme was lost because the main enzyme was separated from its coenzyme during dialyzation. Thus, it was established later that the extracellular enzyme zymase, secreted by yeast cells, carries out the process of fermentation.
