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.
Yeast will ferment in anaerobic conditions (without oxygen) to produce energy in the form of ethanol and carbon dioxide. In aerobic conditions (with oxygen), yeast will respire using oxygen to generate energy in the form of ATP.

Example of alcoholic fermentation?
Alcoholic fermentation is a metabolic process in which yeast cells convert sugars into ethanol and carbon dioxide. An example is the production of beer, where yeast ferments the sugars in malted barley to create alcohol. Another example is the production of wine, where yeast ferments the sugars in grape juice to produce alcohol.
Can dead yeast respire?
No, dead yeast cannot respire because respiration is a metabolic process that requires living cells to produce energy. Once yeast cells die, they are no longer capable of carrying out cellular activities like respiration.
What type of microbe is yeast?
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)
Does yeast carry out life processes?
Yes, yeast is a living organism that carries out life processes such as metabolism, growth, and reproduction. Yeast cells have the ability to consume sugars and produce carbon dioxide and alcohol through fermentation, which is an essential process in baking and brewing.
When do humans use fermentation?
Humans use fermentation for various purposes such as producing alcoholic beverages like beer and wine, baking to make bread rise, pickling to preserve vegetables, and producing dairy products like yogurt and cheese. Fermentation is also used in the pharmaceutical and biotechnology industries to produce antibiotics, insulin, and other chemicals.
What happens when yeast respires anaerobically?
Nothing
Yeast respires anaerobically. what is the name of this process in yeast?
Fermentation is the process by which yeast respires anaerobically to produce energy in the form of ATP and fermentation byproducts such as ethanol and carbon dioxide.
What is produced when yeast respires anaerobically?
Yeast produces ethanol (alcohol) and carbon dioxide when it respires anaerobically. This process is commonly known as alcoholic fermentation and is used in baking and brewing industries.
Is yeast what makes bread rise?
Yeast respires, producing carbon dioxide that makes the bread rise
What do they use to make alcohol?
Yeast and sugar naturally ferments into alcohol.
True or False the main difference between a Lager and an Ale is the type of yeast used?
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.
Can yeast produce gas?
Yes, it respires and releases carbon dioxide; this causes bread to rise.
Can yeast produce CO2 with out sugar?
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.
What is given off when yeast ferments sugar?
Bubbles of CO2 comming out of the solution
What gas does yeast give off?
It gives off carbon dioxide which proves that it respires.
When yeast ferments the sugar in a bread mixture what is produced that causes the bread dough to rise?
C02 babe
Do you expect yeast to produce a gas when sugar is available?
Yes, in the presence of sugar, yeast ferments releasing carbon dioxide (which makes the bubbles in bread dough).
