Fermentation releases energy without using oxygen
Respiration involves breaking down sugar with the use of oxygen to produce energy more efficiently, while fermentation is an anaerobic process that breaks down sugar without oxygen to produce energy less efficiently. Both processes result in the production of ATP, the cell's main energy source.
Yeast produces primarily carbon dioxide and alcohol (ethanol) as byproducts when consuming sugar through the process of fermentation. This is why yeast is commonly used in baking and brewing to help with leavening and fermentation.
The process of fermentation requires microorganisms such as yeast or bacteria, a source of sugar or carbohydrates, and an oxygen-free environment. The microorganisms break down the sugars to produce energy, along with byproducts such as alcohol or acids.
Fermentation refers to catabolic processes where organic molecules, such as sugars or amino acids, are broken down to produce energy without the use of a membrane-bound electron transport chain. Depending upon the organism, fermentation can occur in the presence (aerobic) and/or in the absence (anaerobic) of oxygen. Fermentation pathways produce byproducts such as carbon dioxide, ethanol (alcohol), or organic acids (lactic acid or acetic acid, for example). Yeast cells can ferment sugar and in the process produce carbon dioxide and alcohol. Lactobacillusbacteria can ferment the sugar lactose and produce lactic acid; this is how yogurt is made. Wine vinegar is produced by bacteria that ferment the sugars in grape juice and produce acetic acid. Fermentation is sometimes called anaerobic respiration, but microbiologists disagree with this usage. The term respiration refers to energy-yielding metabolic processes that involve a membrane-bound electron transport chain.
Fermentation is the anaerobic (without oxygen) respiration of sugar by yeast. This correctly indicates that oxygen is not used in the process, but its incorrect to say the absense of oxygen is required. Brewers yeast will ferment anaerobically in the presence of glucose at concentrations of > 1g/l. Brewers yeast has a high alcohol tolerance and produces alcohol as an inhibitor to competitive organisms. Once all the glucose is consumed brewers yeast will consume the alcohol. This phenomenom is known as the Crabtree Effect
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.
It produces sugar.
the sugar has power over fermentation. fermentation can not continue without sugar or yeast

Respiration involves breaking down sugar with the use of oxygen to produce energy more efficiently, while fermentation is an anaerobic process that breaks down sugar without oxygen to produce energy less efficiently. Both processes result in the production of ATP, the cell's main energy source.
In the absence of oxygen, sugar can be broken down through a process called fermentation. During fermentation, sugar is converted into energy, alcohol, and carbon dioxide. This process is commonly used in baking (yeast fermentation) and in the production of alcoholic beverages.
Sugar fermentation is a metabolic process where sugar molecules are broken down by microorganisms such as yeast or bacteria in the absence of oxygen to produce energy. This process typically results in the formation of alcohol and carbon dioxide as byproducts. Sugar fermentation is commonly used in food production, such as in the making of bread, beer, and wine.
Sugar- which is the food for yeasts. Fermentation is yeast consuming sugar, and producing carbon dioxide and alcohol as a waste product.
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.
Yeast "eats" sugar, producing alcohol and CO2 (carbon dioxide).
I don't believe so. PLANT CELLS and such can produce ATP anaerobically in complete darkness; but chloroplasts are mechanisms inside that cell whose sole purpose is to produce glucose sugar and ATP for the cell. So without light, chloroplasts don't have a job to do.
The chemical formula for anaerobic fermentation to produce ethanol from sugar is:C6H12O6 → 2C2H5OH + 2CO2The process creates 2 moles of carbon dioxide for each mole of sugar used.
