What else can I help you with?
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).
Where can pyruvate dehydrogenase be found?
Pyruvate dehydrogenase is typically found in the mitochondria of eukaryotic cells. It plays a critical role in the conversion of pyruvate into acetyl-CoA, a key step in the process of aerobic respiration.
What compound that is derived from glucose actually enters the Krebs cycle?
Acetyl-Coenzyme A (Acetyl-CoA) is the compound the enters the Kreb's cycle and reacts with oxaloacetate. It is dervied from the pyruvate, produced in glycolysis, that has gone through decarboxylation and has conezyme A attached to it.
In glycolysis what is the first three carbon compound produced?
The first three-carbon compound produced in glycolysis is glyceraldehyde-3-phosphate (G3P) from the six-carbon glucose molecule. This occurs after the glucose molecule is broken down into two molecules of pyruvate.
Can you reverse pyruvate decarboxylation?
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.
Is pyruvate and pyruvic acid the same thing?
Yes, pyruvate and pyruvic acid refer to the same compound. Pyruvate is the ionized form of pyruvic acid, which is a key molecule in the process of glycolysis and plays a crucial role in cellular respiration.

What is a three carbon compound that is produced during glycolosis?
The end result of glycolysis is a three-carbon product called pyruvate. However, three-carbon intermediates such as glyceraldehyde-3-phosphate and dihydroxyacetone phosphate are also produced and consumed during the process.
What three carbon compound is the most common end product of glycolysis?
Pyruvate is the most common end product of glycolysis.
What enzyme converts pyruvate into acetyl-CoA?
The enzyme that converts pyruvate into acetyl-CoA is pyruvate dehydrogenase. This multienzyme complex is responsible for catalyzing the conversion of pyruvate into acetyl-CoA, which is a key step in the metabolism of carbohydrates to produce energy.
What are the key differences in the metabolic pathways of glucose and pyruvate?
The key differences in the metabolic pathways of glucose and pyruvate are that glucose is broken down through glycolysis to produce pyruvate, which can then enter the citric acid cycle to produce energy in the form of ATP. Pyruvate, on the other hand, can be converted into acetyl-CoA before entering the citric acid cycle. Additionally, pyruvate can also be converted into lactate or ethanol through fermentation pathways.
Where can pyruvate dehydrogenase be found?
Pyruvate dehydrogenase is typically found in the mitochondria of eukaryotic cells. It plays a critical role in the conversion of pyruvate into acetyl-CoA, a key step in the process of aerobic respiration.

Is pyruvate an organic molecule?
A pyruvate is the salt of pyruvic acid, an organic acid, so yes.
What is pyruvate kinase?
Pyruvate kinase deficiency (PKD) is part of a group of disorders called hereditary nonspherocytic hemolytic anemias.
What are the key steps illustrated in the pyruvate oxidation diagram?
The key steps illustrated in the pyruvate oxidation diagram include the conversion of pyruvate into acetyl-CoA, which then enters the citric acid cycle to produce energy in the form of ATP. This process involves the removal of a carbon dioxide molecule and the generation of NADH and FADH2, which are important molecules for energy production in the cell.
In glycolysis what is the first three carbon compound produced?
The first three-carbon compound produced in glycolysis is glyceraldehyde-3-phosphate (G3P) from the six-carbon glucose molecule. This occurs after the glucose molecule is broken down into two molecules of pyruvate.
