the krebs cycle
The breakdown of pyruvic acid in the presence of oxygen is called aerobic respiration. At the beginning of aerobic respiration, acidic acid bonds to a molecule called coenzyme A to form Acetyl CoA.
Pyruvic acid, also called pyruvate, is produced during glycolysis when the glucose molecule is split.
Pyruvic acid breakdown occurs through a process called pyruvate oxidation, which takes place in the mitochondria. During this process, pyruvate is converted into acetyl-CoA, releasing carbon dioxide and producing NADH. Acetyl-CoA then enters the Krebs cycle to generate more ATP.
Pyruvic acid can be prepared from tartaric acid through a process called pyrolysis, where tartaric acid is heated under controlled conditions to break down into pyruvic acid and other byproducts. The pyruvic acid can then be isolated and purified from the reaction mixture using various separation techniques.
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.

Pyruvic acid, also called pyruvate, is produced during glycolysis when the glucose molecule is split.
The pathway in which two molecules of pyruvic acid are produced is called glycolysis. This process occurs in the cytoplasm of cells and involves the breakdown of glucose into two molecules of pyruvate, along with the production of ATP and NADH.
Pyruvic acid breakdown occurs through a process called pyruvate oxidation, which takes place in the mitochondria. During this process, pyruvate is converted into acetyl-CoA, releasing carbon dioxide and producing NADH. Acetyl-CoA then enters the Krebs cycle to generate more ATP.
The pyruvic acid that is produced by glycolysis is used as the initial input for the Krebs Cycle (also called citric acid cycle). In the initial step of the Krebs Cycle, the pyruvic acid is converted to acetyl-CoA via pyruvate decarboxylation. This continues a series of chemical reactions leading to the production of 2 ATP molecules.
It is the carboxylate ion of pyruvic acid, called pyruvate (3C), which passes into the mitochondrial matrix; it loses 1 carbon (as CO2) in the link reaction, & the remaining 2C product enters the citric acid cycle for final breakdown of the carbon chain.
Pyruvate is the most common end product of glycolysis.
The anaerobic process of splitting glucose to form pyruvic acid is called glycolysis. The citric acid cycle is a series of reactions in aerobic respiration that begins and ends with the same 6 carbon compounds.
fermentation
Pyruvic acid (or pyruvate) is simply one of the compounds in the metabolic pathway from sugars to carbon dioxide and water. From pyruvate (a three cabon unit) either one of two reactions can occur. It can react to form lactose or lose a carbon dioxide molecule to become a two carbon unit and enter the Krebs cycle.
Precisely, it is called pyruvate decarboxylation. The COOH group Pyruvate is removed as CO2, and Acetyl CoA from Coenzyme A is added in an NAD+ dependent manner by the enzyme decarboxylase.
at the end of glycolysis, there is 2 G3P molecules. there is also 2 CO2, 2ATP, 2 NADH
