Question

Action of yeast on dough

Answer 1

anaerobic respiration is done by yeast in dough and produce carbon dioxide which makes Digg flopy and produce acids which taste sour.

Answer 2

Yeast is a single celled, microscopic fungi that break down sugars present in the dough. It produces carbon dioxide through anaerobic respiration that is trapped in the dough causing the dough to rise. This dough is then used for various purposes of baking e.g. in making of bread. The process by which yeast convert carbohydrates into carbon dioxide and alcohol is known as fermentation. Yeast act as a catalyst in the process of fermentation.
