Pyruvate decarboxylation is an irreversible reaction in cellular metabolism where pyruvate is converted into acetyl-CoA and carbon dioxide, primarily in the mitochondria. This process is catalyzed by the pyruvate dehydrogenase complex and is a key step linking glycolysis to the citric acid cycle. Due to its irreversibility, pyruvate decarboxylation cannot be reversed under normal physiological conditions, as the release of CO2 makes it energetically unfavorable to revert the reaction.
What else can I help you with?
Name a molecule that joins in a reaction to make acetyl-coa?
Pyruvate is a molecule that joins in a reaction to form acetyl-CoA through the process of pyruvate decarboxylation.
Is Co2 released during oxidation of pyruvate to acetyl CoA?
Yes, during the oxidation of pyruvate to acetyl CoA in the mitochondria, CO2 is released through decarboxylation reactions. This process is part of the pyruvate dehydrogenase complex, where pyruvate is converted to acetyl CoA, releasing CO2 as a byproduct.
Where does pyruvate grooming occur?
Pyruvate grooming occurs in the mitochondria of eukaryotic cells. After glycolysis, pyruvate, produced in the cytoplasm, is transported into the mitochondria, where it is converted into acetyl-CoA. This process involves the decarboxylation of pyruvate and the production of NADH. The acetyl-CoA then enters the citric acid cycle for further energy production.
Name the two step process where pyruvate is converted to a two carbon compound releasing carbon dioxide. Then the electrons are transferred from a molecule of NADH to the two carbon compound producing?
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).
What happens immendiately after pyruvate is brought into the mitochondria?
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.
What does Decarboxylation of pyruvate produces?
decarboxylation means removal of co2 from the reaction
Which of the following choices is responsible for the decarboxylation in the pyruvate dehydrogenase complex?
Thiamine pyrophosphate (TPP)

What happen immediately after pyruvate is brought in to the mitochondrion?
Immediately after pyruvate enters the mitochondrion, it is converted into acetyl-CoA through a process called pyruvate decarboxylation. This reaction is catalyzed by the pyruvate dehydrogenase complex, which also produces carbon dioxide as a byproduct and reduces NAD+ to NADH. Acetyl-CoA then enters the citric acid cycle (Krebs cycle) to continue cellular respiration and energy production.
Is acetyle coenzyme a formed from the breakdown of pyruvic acid?
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.
What breaks down pyruvate down into carbon dioxide?
Krebs cycle
What metabolites enter the citric acid cycle and is formed in part by the removal of a carbon from one molecule of pyruvate?
Acetyl-CoA is the metabolite that enters the citric acid cycle and is formed in part by the removal of a carbon from one molecule of pyruvate through a process called pyruvate decarboxylation.
What happens immediately after pyruvate brought into the mitochondrion?
Acetyl CoA forms.
