Question
How does the bread become spongy?
✓
Answer
$(i)$ Dough for bread is formed by mixing of baker's yeast Saccharomyces cerevisiaeater, salt and other necessary materials with flour.
$(ii)$ Due to fermentation of carbohydrates by yeast, sugar is converted into carbon-dioxide $(CO_2)$ and ethanol $(C_2H_5OОН).$
$(iii)$ Dough rises up due to $CO_2$ and the bread becomes spongy.
