Understand the process of fermentation: Yeast cells undergo fermentation to convert sugars into energy, producing byproducts in the process.
Identify the byproducts of yeast fermentation: The primary byproducts are ethanol and carbon dioxide.
Consider the role of carbon dioxide: During fermentation, carbon dioxide gas is released, which causes bread dough to rise by creating air pockets.
Differentiate between the byproducts: Ethanol is also produced but evaporates during baking, while carbon dioxide contributes to the rising of the dough.
Conclude the effect of carbon dioxide: Recognize that carbon dioxide is the key product responsible for the rising of bread during yeast fermentation.
