Question

The bread dough rises because of:
A. heat
B. grinding
C. growth of yeast cells
D. Kneading

Answer 1

C. growth of yeast cells

Explanation:

Fermentation is a metabolic process that converts sugar to acids and gases or alcohol. Yeast, a tiny single-celled microorganism, a type of fungus, is an example of a biological raising agent. Yeast is used to make bread dough.

Yeast is a microbe which feeds on sugar. Enzymes in yeast ferment sugar forming carbon dioxide and ethanol. The carbon dioxide makes the bread rise. The ethanol evaporates when the bread is baked.

Option C is the answer.

Answer 2

Answer

the answer is growth of yeast cells

Explanation:

Because bread rises because yeast eats sugar and burps carbon dioxide, which gets trapped by the bread's gluten. The more sugar your yeast eats, the more gas that gets formed, and the higher the bread rises!
