Pyruvate/Pyruvic Acid enters the Citric Acid (Kreb's Cycle) and is the first compound used in ATP generation. Two ATP are directly generated during the cycle. A total of 8 NADH and 2 FADH2 are also generated. The NADH and FADH2 are converted to ATP during Oxidative Phosphorylation (sometimes called the Electron Transport Chain).

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?
acetyl CoA
What enzyme converts pyruvate into acetyl-CoA?
Pyruvate dehydrogenase
What is Pyruvic Acid?
Pyruvate or Pyruvic acid is the end product of the anaerobic portion of glycolysis. If the cell has enough oxygen to run aerobic respiration then pyruvate is converted into acetyl-CoA and carbon dioxide byt eh enzyme pyruvate carboxylase. If there isn't enough oxygen in the cell, then pyruvate is converted to lactic acid in order to free up some of the required reactants(NAD+). This allows anaerobic glycolysis to continue.an ester or salt of pyruvic acid.Pyruvate is an organic acid, which can be formed from glucose through glycolysis, can form lactic acid, provides energy for cells in the citric acid cycle, and can be converted to fatty acids or carbohydrates.
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 pyruvate an organic molecule?
A pyruvate is the salt of pyruvic acid, an organic acid, so yes.
Where is Pyruvate is formed?
glycolysis
Is all of the lactic acid formed in glycolysis oxidized to carbon dioxide and water?
Lactic acid is not formed in glycolysis, pyruvate is (CH3COCOOH). Lactic acid (CH3CHOHCOOH) is formed afterwards in anaerobic repiration, by the reduction of pyruvate. After it is formed it is then transported to the liver where it is oxidised back to pyruvate in the hepatocytes. This then goes on to aerobic respiration entering at the link reaction stage. And yes is eventuallyturned into CO2 and H2O.
Is Pyruvate is a product of glycolysis?
Yes. Pyruvate is a product of glycolysis. This molecule contains three carbons. For every molecule of glucose that enters the glycolytic pathway, two molecules of pyruvate are formed
What happens to pyruvate molecules formed glycolysis in the absence of oxygen?
they will enter the Krebs cycle
What cannot be formed from pyruvate in human beings?
In humans, pyruvate cannot be directly converted into glucose through a process called gluconeogenesis. This is because humans lack the specific enzymes required to convert pyruvate into glucose. Pyruvate can be converted into lactate or acetyl-CoA, which can then enter various metabolic pathways in the body.
Cycle formed after pyruvate is produced?
The citric acid cycle, more commonly known as the Krebs cycle.
What is the substance that enters the Krebs cycle from glycolysis?
In Glycolysis, the final compound formed is Pyruvate. Now, pyruvate has to be transformed to Acetyl-CoA by the substitution of the carboxylic group with a Coenzyme A by pyruvate dehydrogenase. In real terms, Acetyl-CoA is the molecule that "switch on" the Krebs cycle.
Why are only two molecules of NADH formed during glycolysis when it appears that as many as a dozen could be formed?
Most of the free energy from the partial breakdown of glucose remains in pyruvate.
How many ATP are produced by pyruvate?
When pyruvate is formed, approximately twelve molecules of ATP, also known as adenosine triphosphate, are produced. This is only true if pyruvate is the starting point.
Why gluconeogenesis cannot be considered a reversal of glycolysis even though both pathways share reversible reactions?
In glycolysis you get pyruvate (or lactate) as a end product but in gluconeogenesis you get glucose formed from either Fat or Proteins. There are many intermediate steps before pyruvate is formed from Proteins and Fats. So gluconeogenesis cannot be considered as reversal of glycolysis.
Which are products of pyruvate dehydrogenase?
Pyruvate dehydrogenase complex react with pyruvate to form acetyl-CoA
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?
acetyl CoA
