Detailed explanation-1: -Ethanol and carbon dioxide are produced. Yeast can also be used to produce bread. Yeast respires using glucose in the sugar that was added to the dough. Bubbles of carbon dioxide make the bread rise.
Detailed explanation-2: -The process of alcoholic fermentation is used in making bread dough. Bread dough rises as yeast processes sugar and produces carbon dioxide, the gas that makes the dough rise.
Detailed explanation-3: -Yeast is a living organism and needs to respire to make energy! As it respires, it produces carbon dioxide as a waste product. It is this gas that causes the bread dough to rise!
Detailed explanation-4: -Anaerobic respiration in plants and yeast is different from the same process in muscle cells. Ethanol and carbon dioxide are produced. Anaerobic converts glucose into ethanol and carbon dioxide in yeast cells due to different circumstances within the different types of cells, instead of lactic acid as in muscle cells.
