Yeast has the ability to cause a form of alcoholic fermentation. This is what is used to make the bread dough to rise and it produces ethanol.
Alcoholic fermentation
lactic acid fermentation helps make yogurt, cheese, and it also occurs in muscles which is why you may get that burning sensation in your legs while excersizing. Alcoholic fermentation makes wine and bread using yeast.
Yeast, most commonly Saccharomyces cerevisiae, is used in baking as a leavening agent, where it converts the fermentable sugars present in the dough into carbon dioxide. This causes the dough to expand or rise as the carbon dioxide forms pockets or bubbles. Brewer's yeast (also known as brewing yeast) can mean any live yeast used in brewing. It can also mean yeast obtained as a by-product of brewing, dried and killed, and used as a dietary supplement for its B vitamin content.
The carbon dioxide causes it to rise. Hope this helps!
It's not a type, it's a outcome of fermentation. A.K.A. a waste product
Fermentation - creates bubbles of carbon dioxide... which causes the dough to rise, and gives bread light, open texture.
Sugar- which is the food for yeasts. Fermentation is yeast consuming sugar, and producing carbon dioxide and alcohol as a waste product.
Carbon dioxide.
Lactic Acid. The overall name of the burning feeling is lactic acid fermentation:-)
Muscles use aerobic respiration to metabolize the energy they need to function. When they have insufficient oxygen to metabolize all the energy they need, they use anaerobic respiration in the form of fermentation. The Lactic acid which is created as a by product of fermentation builds up in the muscles and causes soreness.
