Question

Which fermentation product is important for making bread rise?

a) Lactic acid
b) Alcohol
c) Acetic acid
d) Carbon dioxide

Answer 1

Carbon dioxide is the fermentation product important for making bread rise, created during alcoholic fermentation by yeast.

Step-by-step explanation:

The fermentation product that is important for making bread rise is carbon dioxide (CO2). During the process of alcoholic fermentation, yeast breaks down sugars such as glucose in the absence of oxygen to produce ethanol and carbon dioxide. The carbon dioxide gas released during fermentation creates bubbles in the dough, which causes the dough to expand, or rise. The gas is trapped within the dough and results in the light, airy texture of bread once it is baked. This is why bread dough rises and takes on its characteristic fluffy appearance after baking.
