Alcohol arguably the most important part of wine production and is the result of anaerobic respiration/ fermentation. Aerobic respiration results in vinegar.
Fermentation.
When yeast cells ferment it builds up gases. That is the reason why champagne might explode from the bottle just after opening. It is also why there is a distinct popping noise when wine is opened.
Yeast eating sugars and excreting waste. Alcohol is yeast waste.
Alcohol and carbon dioxide are two waste products that are given off by a fermenting yeast.
Yeast cannot produce their own foods. The yeast do not have chlorophyll. Yeast must rely on other ways and sources to get food. Yeast mostly feed on sugar.
No Yeast cells produce spores which serve the same function as seeds
yes
The yeast will break down the glucose which produces Carbon dioxide + Ethanol + Energy during anaerobic respiration and the process is also known as 'fermentation'. Carbon dioxide and Ethanol are the waste products. During aerobic respiration, the yeast will produce the same products as we produce such as Carbon dioxide, water and energy.
No, combining yeast with sugar will not produce gas. Yeast must be dissolved in water with starch or sugar in order to begin fermentation producing CO2 gas.
It creates it when it "eats" the sugars in the flour mixture
Yeast will produce gas if sugar, water, and warmth are available as long as the yeast is still alive. If it is too old or has been too hot and the yeast has died it won't create the gas.
It would fizz and smell because of microbial growth. The soup is spoiling. Yeast and some bacteria produce gas as waste products of their metabolism.
