Yeast is a living, microscopic, single-cell organism that, as it grows, converts its food (through a process known as fermentation) carbon dioxide. This trait is what endears yeast to bread bakers. The art of bread making needs the carbon dioxide produced by yeast in order for certain doughs to rise. To multiply and grow, all yeast needs is the right environment, which includes moisture, food (in the form of sugar or starch) and a warm, nurturing temperature (70° to 85°F is best).
The breakdown of the yeast causes effervescence, the giving off of gasses which get trapped in the dough, and the lump of dough expands. As the bread is usually in a tin, the only way it can expand is upwards. A lump of dough not in a tin will expand sideways as well as upwards.
Yeast holds a chemical [not dangerous to mankind] and when heated it rises just like smoke when cooked by its self it can catch fire at just 35 degrees.
Yeast is a living organism. It feeds off the sugar in the bread and respires, meaning that it takes in oxygen and gives out carbon dioxide. The carbon dioxide given out is the 'air' inside bread.

∙ 8y agoYeast is used in baking as a leavening agent, where it converts the fermentle sugars present in the dough in carbon dioxide. This causes the dough to expand or rise as the carbon dioxide forms pockets or bubbles. When the dough is baked it "sets" and the pockets remain, giving the baked

∙ 7y agoYeast makes bread rise. When yeast releases carbon dioxide as it grows and metabolizes the available sugar. The released gas helps make the bread fluffy and soft. Baking soda is used for similar purposes in biscuits and cakes. Yeast can also add a pleasant flavor to the bread (as long as you don't use too much or let the bread rise too long).

Why sugar is important to the growth of yeast?
This is actually not a chemical reaction. Yeast are living organisms and they use sugar as an energy source, so if you put yeast and sugar together the yeast will consume the sugar and give off carbon dioxide. This is why breads made with yeast rise and have small holes in the bread after it is baked - the holes are where small bubbles of carbon dioxide were trapped.

When did medieval girls learn to make bread?
Girls typically would learn to bake starting at about the age of seven. Not all girls learned to bake bread, because most people did not have ovens, and many people did not even have access to ovens. In such cases, bread was not baked at home. Girls were apprenticed to bakers at about the age of seven, and could become professional bakers. In some places, they could even become guild members. Please use the links below for more information on guilds.
