The practical importance of high (i.e. close to 1) transference numbers of the charge-shuttling ion (i.e. Li+ in lithium-ion batteries) is related to the fact, that in single-ion devices (such as lithium-ion batteries) electrolytes with the transfer number of the ion near 1, concentration gradients do not develop. A constant electrolyte ...
In lactic acid fermentation, each pyruvate molecule is directly reduced by NADH. The only byproduct from this type of fermentation is lactate . Lactic acid fermentation is used by human muscle cells as a means of generating ATP during strenuous exercise where oxygen consumption is higher than the supplied oxygen.
The mixed acid fermentation pathway in E. coli. [1] [2] End products are highlighted in blue.In biochemistry, mixed acid fermentation is the metabolic process by which a six-carbon sugar (e.g. glucose, C 6 H 12 O 6) is converted into a complex and variable mixture of acids.
Fermentation of feedstocks, including sugarcane, maize, and sugar beets, produces ethanol that is added to gasoline. [15] In some species of fish, including goldfish and carp, it provides energy when oxygen is scarce (along with lactic acid fermentation). [16] Before fermentation, a glucose molecule breaks down into two pyruvate molecules .
The origin of aerobic fermentation, or the first step, in Saccharomyces Crabtree-positive yeasts likely occurred in the interval between the ability to grow under anaerobic conditions, horizontal transfer of anaerobic DHODase (encoded by URA1 with bacteria), and the loss of respiratory chain Complex I. [9] A more pronounced Crabtree effect, the ...
Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.

Metabolic acidosis is compensated for in the lungs, as increased exhalation of carbon dioxide promptly shifts the buffering equation to reduce metabolic acid. This is a result of stimulation to chemoreceptors, which increases alveolar ventilation, leading to respiratory compensation, otherwise known as Kussmaul breathing (a specific type of ...
