The carbon dioxide gas produced by yeast during alcoholic fermentation causes bread dough to rise.

Explanation:

Yeast undergo alcoholic fermentation, during which ATP, carbon dioxide gas, and ethanol are produced.

In the diagram below, glycolysis is the first step and produces ATP and pyruvic acid , or pyruvate , which is converted to acetaldehyde by the enzyme pyruvate decarboxylase, which produces #"CO"_2# . The acetaldehyde is converted to ethanol by the enzyme alcohol dehydrogenase.
