Pyruvate

Definition

noun

The carboxylate anion of pyruvic acid.


Supplement

Pyruvate is the end product of glycolysis, which is converted into acetyl coA that enters the Krebs cycle when there is sufficient oxygen available. When the oxygen is insufficient, pyruvate is broken down anaerobically, creating lactate in animals (including humans) and ethanol in plants.


Word origin: PYR(O)– + Latin ūva, grape (from its being produced by the dry distillation of racemic acid, originally derived from grapes) + -ate.

Related forms: pyruvic (adjective).
Related phrases: phosphoenol pyruvate, pyruvate decarboxylation.

See also: pyruvic acid, cellular respiration, glycolysis.

how anoxybiont choose the pathway

There are many anaerobes which choose to obtain energy from glycolosis. There are two products from the pyruvate, one is alcohol like the yeast, and the other one is lactic acid like the lactobacillus. My question is that what‘s the evolution of choosing these two pathways ...

Converting to energy source- glycolysis etc..

So here is what i know so far glycolysis --> pyruvate oxidation --> citric acid cycle --> electron transport chain --> produces a total of 32 ATP So here is what i am confused about. For plants, they go through photophosphorylation instead ...

cellular respiration???

... Keeping it simple cellular respiration starts with a molecule of glucose, which is a six carbon sugar. It is converted to two molecules of pyruvate (Pyruvic acid) in the first step, with the formation of two molecules of ATP and two molecules of NADH+H. Both pyruvate molecules are carried ...

aerobic and anaerobic glucose degeneration in a cell

... can use. In Anaerobic respiration/fermentation glucose is broken down through investment of ATP into several intermediates eventually creating pyruvate and 2 net ATP. Because of the lack of oxygen this reaction does not proceed to normal aerobic respiration in the mitochondria but instead continues ...
