Question

Yeast raises bread dough and makes it fluffy by releasing gas.

• A. oxygen
• B. carbon dioxide
• C. nitrogen
• D. carbon monoxide

Answer 1

The correct option is B carbon dioxide

Yeast is a fungus used for making bread. It is mixed with the dough, where it grows actively and releases carbon dioxide. This carbon dioxide helps in the rising of the dough. When this dough is subjected to high baking temperatures, carbon dioxide escapes from the dough resulting in soft and fluffy bread.
