What intermediary metabolites enters the citric acid cycle and is formed in part by the removal of a carbon CO2 from one molecule of pyruvate?
The intermediary metabolite that enters the citric acid cycle after the removal of a carbon CO2 from pyruvate is acetyl-CoA. This process is catalyzed by the enzyme pyruvate dehydrogenase, and acetyl-CoA is a key molecule that fuels the citric acid cycle by providing the acetyl group for the first step with oxaloacetate.
Is pyruvate a chiral molecule?
Yes, pyruvate is a chiral molecule. It has three carbon atoms, and the central carbon is chiral due to its four different substituents: a carboxyl group, a carbonyl group, a methyl group, and a hydrogen atom.
Pyruvate is made of how many carbons?
It has three carbon atoms.Pyruvate is the anion of pyruvic acid: CH3C(=O)COOH , IUPAC name: 2-oxopropanoic acid
What are the substrates and products of pyruvate oxidation?
The substrate of pyruvate oxidation is pyruvate, a three-carbon molecule derived from glycolysis. The products of pyruvate oxidation are acetyl-CoA, which is a two-carbon molecule, and carbon dioxide. This process occurs in the mitochondria and is a crucial step in the aerobic respiration pathway.
How many molecule of carbon dioxide are produce when Krebs cycle operates once?
One molecule of glucose is broken down into two molecules of pyruvate during glycolysis. Each pyruvate molecule then enters the Krebs cycle and is fully oxidized to produce three molecules of carbon dioxide. Therefore, in total, six molecules of carbon dioxide are produced when the Krebs cycle operates once.

This process is catalyzed by the enzyme pyruvate dehydrogenase, and acetyl-CoA is a key molecule that fuels the citric acid cycle by providing the acetyl group for the first step with oxaloacetate.
How many C atoms are in a molecule of pyruvate?
There are three carbon atoms and three oxygen atoms in each pyruvate molecule.
How many total carbon are lost as pyruvate is oxidized?
During the oxidation of pyruvate, a total of 2 carbon atoms are lost in the form of carbon dioxide. Pyruvate, a 3-carbon molecule, is converted into acetyl-CoA, which is a 2-carbon molecule, leading to the release of 2 carbon atoms as CO2.
Is pyruvate a chiral molecule?
Yes, pyruvate is a chiral molecule. It has three carbon atoms, and the central carbon is chiral due to its four different substituents: a carboxyl group, a carbonyl group, a methyl group, and a hydrogen atom.

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).
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.
How many carbons does 1 molecule of pyruvate have?
Pyruvic acid is C3H4O3 and has 3 carbon atoms.
How many bonds are in 2 pyruvate molecule?
Each pyruvate molecule has a total of 3 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms, resulting in a total of 6 carbon-hydrogen (C-H) bonds, 2 carbon-oxygen (C-O) bonds, and 1 oxygen-hydrogen (O-H) bond. Therefore, a single pyruvate molecule contains 9 bonds. Consequently, 2 pyruvate molecules would have a total of 18 bonds.
What are the substrates and products of pyruvate oxidation?
The substrate of pyruvate oxidation is pyruvate, a three-carbon molecule derived from glycolysis. The products of pyruvate oxidation are acetyl-CoA, which is a two-carbon molecule, and carbon dioxide. This process occurs in the mitochondria and is a crucial step in the aerobic respiration pathway.
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.
What is a 3 carbon molecule produced when glucose isbroken in half during glycolysis?
PGA,PGAL,Pyruvate
