Best Answer: Yeast is a microscopic plant that feeds on sugar. It is used in brewing, breadmaking, and as a nutritional supplement (B vitamin complex). There are different types--brewer's yeast, bread yeast, etc.. The yeast in a yeast infection is in the same family, but you wouldn't want to cook with it.any types of yeasts are used for making many foods: Baker's yeast in bread production, brewer's yeast in beer fermentation, yeast in wine fermentation and for xylitol[19] production. Yeasts are also one of the most widely used model organisms for genetics and cell biology.
In order to grow, yeast need glucose (C 6 H 12 O 6) or sucrose (table sugar, C 12 H 22 O 11), water (H 2 O) and warm temperatures. As yeast digest sugar, they turn into alcohol. In the process they give off carbon dioxide (CO 2) gas. The alcohol dissolves in the water and the gas escapes into the air. Yeast is used to make bread.
