Yeast is a great example of Cellular Respiration. In a normal (Anaerobic) reaction, yeast breaks down sugar to release carbon dioxide and ethyl alcohol.
When oxygen is added to the sugar and yeast, Aerobic respiration occurs. This releases more energy and less carbon dioxide than Anaerobic respiration. Of course, the reactions have to occur very close to 40 degrees Celsius or the yeast will die. If temperatures are too low, the reaction will not occur.
The presence (or absence) of oxygen determines whether or not yeast will ferment or undergo cellular respiration.
usually cooking: yeast (a bacteria) ferments in dough during baking- bread produced grape juice ferments- wine is produced milk ferments- yogurt is produced.
yeast respires so it can reproduce and the energy is used for reproduction
Yes.It moves (albeit very, very slowly), respires, senses, grows, reproduces, excretes and takes in nutrition.
Yeast is made up of molds and mushrooms which are members of the Kingdom of Fungi.The type of Microbe yeast uses is carbon dioxide which produces bubbles in bread (make it rise) and Ethanol produced (Evaporates when baking)
The microbe in bread is yeast. Yeast is a living substance and it is useful in bread because it respires and creates bubbles that makes the bread rise. this happens when the bread dough is left in a warm area to rise. The yeast also makes alcohol during this proses but this evaporates when the bread is cooked. the cooking proses also kills the yeast.

Nothing
Yeast respires, producing carbon dioxide that makes the bread rise
I think it is called Fermentation. -Alayna Nikole
Yeast and sugar naturally ferments into alcohol.
usually cooking: yeast (a bacteria) ferments in dough during baking- bread produced grape juice ferments- wine is produced milk ferments- yogurt is produced.
True Lager is distinguished from ale by its yeast. Lager yeast ferments at lower temperatures and flocculates on the bottom of the fermenting vessel, while ale yeast ferments at higher temperatures and settles on the tops of fermentation tanks.
Yes, it respires and releases carbon dioxide; this causes bread to rise.
yeast is a living organism and every living organism needs energy, and yeasts energy comes from sugar.when the yeast respires the sugar it will cause the yeast to give off co2.
It gives off carbon dioxide which proves that it respires.
