Question

Yeast is used in the production of

• A. bread and beer
• B. cheese and butter
• C. citric acid and lactic acid
• D. lipase and pectinase

Hint:

Yeast is a unicellular fungus. Reproduction in yeast occurs asexually through budding or division. For multiplication and growth, yeast is dependent on oxygen and food in the form of sugar. The byproduct of sugar after consumption by yeast is an important commercial substance.  

Answer 1

The Correct Option is A

Yeast (Saccharomyces cerevisae) is used to produce bread and beer.

Some important characteristic properties of yeast are:

• Yeast is a eukaryotic and single-celled fungus. 
• The commonly used species of yeast is Saccharomyces cerevisiae, also known as baker's yeast.
• The yeast is used in the production of fermented products like cakes, bread, and alcohol.
• Yeast converts the fermentable sugars present in the substrate to produce carbon dioxide and ethanol.
• The carbon dioxide gas makes the dough of bread and cake soft and fluffy. 
• There are pores in the bread and cakes which is due to the carbon dioxide gas bubbles which get trapped during the process of baking.
