What is the anaerobic process where cells convert pyruvic acid into carbon dioxide and ethyl alcohol?
The anaerobic process where cells convert pyruvic acid into carbon dioxide and ethyl alcohol is called alcoholic fermentation. This process occurs in yeast and some bacteria in the absence of oxygen.
In which of these does alcoholic fermentation occur?
Alcohol fermentation is done by yeast and some kinds of bacteria. These microorganisms convert sugars in ethyl alcohol and carbon dioxide. Alcoholic fermentation begins after glucose enters the cell. The glucose is broken down into pyruvic acid. This pyruvic acid is then converted to CO2, ethanol, and energy for the cell. Humans have long taken advantage of this process in making bread, beer, and wine. In these three product the same microorganism is used: the common yeast or Saccharomyces Cerevisae.http://www.tempeh.info/fermentation/alcohol-fermentation.php
Which two compounds react during fermentation?
During fermentation, the two compounds that typically react are glucose (a type of sugar) and yeast. The yeast consumes the glucose through a process called glycolysis to produce ethanol and carbon dioxide.
Do most organisms perform fermentation using a chemical reaction that converts pyruvic acid to lactic acid?
No, not all organisms perform fermentation by converting pyruvic acid to lactic acid. Some organisms, such as yeast, perform fermentation by converting pyruvic acid to ethanol and carbon dioxide through a process called alcoholic fermentation.

Is fermentation a process by which vesicles release their contents outside the cell?
no During fermentation glucose is converted into ethyl alcohol and carbon dioxide by the enzyme Zymase. This zymase enzyme is released from yeast cells during fermentation. Therefore, the answer is yes.
What is the relationship between glycolysis and fermentation?
The two processes, fermentation and glycolysis, use the same pathways to convert glucose to pyruvic acid (see related links). However, in yeast under anaerobic conditions, the alcohol fermentation process* differs by a single additional step, in which the pyruvic acid is converted to ethanol (ethyl alcohol). * This process differs from the fermentation that occurs within cells. Although the cellular process also uses the pyruvic acid from glycolisis, ethanol or lactic acid is commonly produced.
What is lactic acid fermentaion?
Lactic acid fermentation is a metabolic process where glucose is converted into lactic acid in the absence of oxygen. This process is carried out by some bacteria and fungi, including lactobacilli, and is utilized in various food production processes such as yogurt and sauerkraut fermentation.
When an organism such as yeast lives by fermation it converts the pyruvic acid from glycolsis into a different compound such as alcohol Why doesn't it secrete pyruvic acid directly?
Yeast metabolizes pyruvic acid through fermentation to produce alcohol because this process enables it to regenerate NAD+, necessary for sustaining glycolysis in the absence of oxygen. By converting pyruvic acid into alcohol, yeast can maintain its energy production despite limited oxygen availability. Additionally, secreting pyruvic acid directly would not serve the same energy-generating purpose as fermentation.
What is produced by yeast during fermentation?
Yeast produces ethanol (alcohol) and carbon dioxide as byproducts during fermentation. These byproducts are what give fermented foods and beverages their characteristic flavor and texture.
What type of fermentation occurs in yeast and some plants?
alcoholic fermentation, also referred to as ethanol fermentation, is a biological process in which elements such as glucose, fructose, and sucrose are converted into cellular energy and thereby produce ethanol and carbon dioxide as metabolic waste products.
What does yeast form during fermentation?
Yeast produces carbon dioxide and alcohol during fermentation. The carbon dioxide is released as a gas, causing the dough to rise in baking or creating bubbles in alcoholic beverages.
