Fermentation in Biological Definition

Cellular respiration

... typically only aerobic respiration will occur. fermentation is a process in which pyruvate is partially ... of different compounds. Textbook examples of fermentation products are ethanol (drinkable alcohol), ... such as butyric acid and acetone . Although fermentation produces no ATP, it is useful to the cell ...

Enzyme

... and saliva were observed. Studying the fermentation of sugar to alcohol by yeast, Louis Pasteur came to the conclusion that this fermentation was catalyzed by " ferments " in the yeast. In ... yeast cells by Eduard Buchner , proving that the fermentation was caused by molecules that functioned even ...

Fermentation

... In its strictest sense, fermentation (formerly called zymnosis ) is the ... such as glucose, without net oxidation. fermentation yields lactate , acetic acid , ethanol , or some other simple product. fermentation is also used much more broadly to refer to the ...

Metabolism

... respiration , Cori cycle Lactic acid fermentation fermentation Ethanol fermentation Anabolism Anabolic pathways ...

Alcohol

... versatile intermediates. Sources Many alcohols can be created by fermentation of fruits or grains with yeast , but only ethanol is commercially ... alcohol via the last two methods is shown: Industrial fermentation : using glucose from the hydrolysis of starch , in the presence of ...

Citric acid cycle

... provides precursors for many compounds such as certain amino acids , and some of its reactions are therefore important even in cells performing fermentation . Contents showTocToggle("show","hide") 1 History 2 Location of cycle and inputs and outputs 3 Major metabolic pathways ...

Ethyl alcohol

... art of distillation , such as Geber (721-815) and Al-Razi (864-930). Production Ethanol for use in alcoholic beverages is produced by fermentation : it is a product of sugar metabolism in certain species of yeast in the absence of oxygen . The process of culturing yeast under conditions ...

Glycolysis

... depends upon the organism and the conditions, most notably the presence or absence of oxygen or other external electron acceptors. In fermentation , the pyruvate and NADH are anaerobically metabolized to yield any of a variety of products. For example, the bacteria involved in making yogurt ...

Louis Pasteur

... he was made administrator and director of scientific studies of the cole Normale Suprieure . Germ theory Louis Pasteur demonstrated that the fermentation process is caused by the growth of microorganisms , and that the growth of microorganisms in nutrient broths is not due to spontaneous generation ....

Microbiology

... by the process of anaerobic fermentation, in which different simple organic molecules are produced. This gave rise to the science of industrial fermentation . In this way it is possible to produce different antibiotics, beer , vinegar and other substances. Bacterial genes have been inserted into ...

Primary nutritional groups

... production of starch from water and CO 2 ). It should be noted that the terms aerobic respiration , anaerobic respiration and fermentation are not referring to primary nutritional groups, but simply reflect the different use of possible electron acceptors in the energy metabolism of ...
