Fermentation is the process of deriving energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound .
change in an organic substance caused by a ferment, such as souring of milk, with little or no oxygen involved, that is, anaerobic respiration

Alcohol fermentation is the formation of alcohol from sugar. Yeast, when under anaerobic conditions, convert glucose to pyruvic acid via the glycolysis pathways, then go one step farther, converting pyruvic acid into ethanol, a C-2 compound.
There is another way that the NADH molecule can be re-oxidized. Anaerobic conditions in yeast convert pyruvate to carbon dioxide and ethanol.

A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end-product, such as ethyl alcohol or lactic acid.
fermentation A catabolic process that produces a characteristic product such as lactic acid or ethanol. Without an electron transport chain, fermentation makes a limited amount of ATP from glucose. See: respiration.
fermentation an anaerobic process in which energy can be released from glucose even though oxygen is not available; occurs in yeast cells.

fermentation (alcoholic) A type of anaerobic respiration that yields carbon dioxide and alcohol; used in commercial fermentation processes, including production of raised bakery dough products and alcoholic beverages.

Fermentation and cellular respiration are anaerobic and aerobic alternatives, respectively, for producing ATP from sugars.
Problem 11: Fermentation
In the absence of oxygen, the primary purpose of fermentation is to:
A. produce amino acids for protein synthesis ...
1856 - Louis Pasteur states that microorganisms produce fermentation.
1858 - Charles R. Darwin and Alfred Wallace independently propose natural selection theories of evolution.
1858 - Rudolf Virchow proposes that cells can only arise from pre-existing cells.
At high D (greater than 0.3/hour), yeast cells switch their metabolism from pure respiration to a mix of fermentation and respiration. This phenomenon of simultaneous respiration and fermentation is known as the Crabtree effect after the physiologist H.G.
Feedback inhibition Fen-Phen FermentationAnaerobic decomposition of an organic compound (e.g., glucose) by a living organism.
That which causes fermentation, as yeast, barm, or fermenting beer.
ferments are of two kinds: (a) formed or organised ferments. (b) unorganised or structureless ferments. The latter are also called soluble or chemical ferments, and enzymes.
There are some cells like yeast that will do a different form of fermentation called alcoholic fermentation, now what they do is instead of converting the pyruvate into a lactate they convert the pyruvate into ethyl alcohol a 2 carbon molecule and carbon dioxide a gas.
This is known as lactic acid fermentation and it is an anaerobic process that does not require oxygen. In this process additional ATP are produced directly from the products of glycolysis.
The glucose:proline signature reveals sensitivity in a number of respiratory deficient mutants, which is atypical for glucose conditions in general since fermentation is generally preferred over respiration when cells are grown on glucose.
It's a whole process called fermentation. Sugars are broken down in an environment without oxygen. It's called anaerobic fermentation. And voila, alcohol. Even though they are single celled, you may find them in colonies. They reproduce very quickly and hang out together.
Digestion breaks down this food into glucose, which then is converted to ATP by either the Kreb's cycle or anaerobic fermentation. This process is never even close to 100% efficient, especially in warm blooded animals.
Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the mitochondria.
