. The gas released during the preparation of bread is


(b)carbon dioxide   


(d)sulphur dioxide


Best Answer

The Correct Option is (b)  

Explanation: CO2 (Carbon dioxide) is released when the bread is baked. During fermentation the yeast cells produce Carbon dioxide rapidly, forming holes in the bread. Yeast contains enzymes that can break down starch into flour; first amylase is used to break down the starch into maltose, and then to use maltase to break down the maltose into glucose.
