Yeast itself causes fermentation, when added to a suitable mix, such as oats (beer), fruit (wines) or a flour mix (dough). This requires the addition of some moisture, warmth and perhaps a bit of sugar.
What happens is that yeast will grow (multiply) and this process releases various gasses and chemicals. This is what causes fruit to become alcoholic, and causes dough to rise so you can bake bread.

What must exist for fermentation to occur?
yeast and sugar.
Which type of fermention occur in yeast?
Alcoholic Fermentation.
Can fermentation happen without yeast?
Yes, fermentation can occur without yeast. Some bacteria, such as Lactobacillus and Pediococcus, are capable of carrying out fermentation processes in certain foods and beverages. Examples include the fermentation of kimchi, sauerkraut, and some types of sourdough bread without the use of yeast.
Is it necessary to add yeast to alcoholic fermentation?
Yes, yeast is necessary for alcoholic fermentation as it converts sugars into alcohol and carbon dioxide. Yeast consumes the sugars in the fermentation process, producing alcohol as a byproduct. Without yeast, the fermentation process cannot occur.
What is it called when yeast respire anaerobically?
fermentation
What type of fermentation is carried out by yeast?
Alcoholic fermentation
Which pathogen causes fermentation?
Yeast is a common microorganism that causes fermentation. Specifically, species of Saccharomyces yeast are often used in fermentation processes, such as brewing beer and making bread.
What is needed to start fermentation?
Conditions of brewery must be sanitary. Bugs and/or bacteria can ruin the batch. The tempurature is important. Cold air is best for fermentation. if you have sanitary conditions, the right tempurature, yeast and sugar wort fermentation should happen.
Why do we use sugar in yeast?
the sugar has power over fermentation. fermentation can not continue without sugar or yeast
How do the products of fermentation in animals differ from yeast?
In animals, fermentation produces lactate or lactic acid as a byproduct, while in yeast, fermentation produces ethanol and carbon dioxide. Lactic acid fermentation does not produce energy as efficiently as ethanol fermentation, which is why animals primarily rely on it during high-intensity exercise when oxygen is limited. Fermentation in animals occurs in muscle cells, while yeast fermentation takes place in yeast cells.
What types of fermentation occurs in bacteria and yeast?
Alcohol fermentation.
What is the raw materials of alcohol fermentation?
The raw materials for alcohol fermentation are generally sugar (such as glucose or sucrose) and yeast. Yeast metabolizes the sugar through the process of fermentation, converting it into alcohol and carbon dioxide. Water is also required for the fermentation process.
