Verified step by step guidance

Understand the process of fermentation: Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation.
Identify the role of yeast in bread making: In bread making, yeast is used to ferment sugars present in the dough. This fermentation process produces carbon dioxide and ethanol as byproducts.
Recognize the importance of carbon dioxide: The carbon dioxide produced during fermentation is crucial for making bread rise. As the gas is released, it gets trapped in the dough, causing it to expand and rise.
Differentiate between the fermentation products: Acetic acid and lactic acid are not involved in the rising of bread. Ethanol is produced during fermentation but evaporates during baking, contributing to the bread's flavor rather than its rise.
Conclude with the correct fermentation product: Based on the role of carbon dioxide in expanding the dough, it is the key fermentation product responsible for making bread rise.
