decarboxylation means removal of co2 from the reaction
CO2, NADH, acetylcoA
mitochondria matrix
Most summaries of the Krebs Cycle will usually indicate that the cycle is an aerobic process (one that requires oxygen) that produces ATP by breaking down glucose.Kreb Cycle shows no oxygen or glucose is used in the cycle and that it does not make much ATP (only one molecule for each acetyl CoA that enters the cycle).
The Swanson Conversion is another term for Pyruvate Decarboxylation. It is part of the process by which cells produce ATP and takes place before the Krebs Cycle. The origin of the name "the Swanson Conversion" is unknown, but the story goes that there was a high school biology teacher named Swanson who wanted something named after himself, so he told his students to put "the Swanson Conversion" down as another name for pyruvate decarboxylation on its wikipedia page and spread the name around the internet to gain it credibility, and now the name is commonly used as a substitute for "pyruvate carboxylation"
Pyruvate is produced at the end of glycoysis and converted into Acetyl CoA and then used in tricarboxylic acid (aka Kreb's, citric acid) cycle to ultimately more ATP.
In glycolysis of cellular respiration, NADH produces 2ATP because one ATP is used to transport a molecule of NADH into the mitochondria and continue with aerobic respiration. However, in pyruvate decarboxylation and the Krebs cycle, each NADH yields 3ATPs. FADH2 yields 2 ATPs.
Acetyl-CoA is produced during the second step of aerobic cellular respiration. In the matrix of the mitochondria pyruvate decarboxylation occurs.
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.
Thiamine pyrophosphate (TPP)
Pyruvate decarboxylation -> Acetaldehyde reduction The product is ethanol. Pyruvate decarboxylation is performed by pyruvate decarxylase with cofactor thiamine pyrophosphate, and the product, acetaldehyde, is reduced by NADH. (Pyruvate decarboxylase is NOT the same as the pyruvate dehydrogenase complex in cellular respiration. Though pyruvate dehydrogenase also decarboxylates pyruvate, but the decarboxlated species immediately reacts with CoA to form acetyl-CoA).
There are very many enzymes involved. A few from glycolysis are: hexokinase and glucokinase, phosphohexose isomerase, phosphofructokinase, pyruvate kinase; from pyruvate decarboxylation are pyruvate dehydrogenase phosphatase and pyruvate dehydrogenase kinase; and a few from the Kreb's cycle are: aconitase, alpha-ketoglutamate dehydrogenase, succinate thiokinase, and fumarase.
Molecular oxygen
After pyruvate is brought into the mitochondria, it undergoes a series of enzymatic reactions called pyruvate decarboxylation. In this process, pyruvate is converted into acetyl-CoA, which can then enter the citric acid cycle (also known as the Krebs cycle or TCA cycle) to produce energy in the form of ATP.
the krebs cycle produces pyruvate as a product to be used by the ATP molecules.
