EVERYDAY SCIENCE

Detailed explanation-1: -As the yeast feeds on the sugar, it produces carbon dioxide. With no place to go but up, this gas slowly fills the balloon. A very similar process happens as bread rises. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough.

Detailed explanation-2: -Yeasts feed on sugars and starches, which are abundant in bread dough! They turn this food into energy and release carbon dioxide gas as a result. This process is known as fermentation.

Detailed explanation-3: -After 24 h CO2 production rates was still high, ranging between 5.9 mL/min (1.5 g yeast and 280 g/L sugar solution) and 5.5 mL/min (5 g yeast and 280 g/L sugar solution) (Figure 2).

Detailed explanation-4: -Bubbles form as the yeast ferment the sugar and release carbon dioxide. Saccharomyces cerevisiae is widely recommended for baking and brewing purposes. When yeast is mixed with sugar and lukewarm water, it will activate the yeast.

Detailed explanation-5: -Yeast needs sugar to produce carbon dioxide . The leavening gas that causes the dough to rise. If there is not enough sugar available, the dough will rise slowly or not at all.
