Which are products of pyruvate dehydrogenase?
Pyruvate dehydrogenase complex react with pyruvate to form acetyl-CoA
Which molecule can be made from acetyl CoA molecules?
Pyruvate
Glycolysis is the breakdown of what organic molecule?
....conversion of glucose to pyruvate.
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 is pyruvate metabolized?
pyruvate is converted into acetyl coA in the mitochondrial matrix
How many ATP molecules does each NADH molecule yield?
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.
Which are products of pyruvate dehydrogenase?
Pyruvate dehydrogenase complex react with pyruvate to form acetyl-CoA
What does one pyruvate produce after the Krebs cycle?
1 atp
What are the Products of the Krebs cycle per molecule of pyruvate?
For one molecule of Pyruvate (pyruvic acid) the Krebs cycle produces 2 molecules of carbon dioxide (CO2), 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP.Also, the change from pyruvate to acetyl CoA produces one NADH and one carbon dioxide molecule; CoA is recycled in and out of the cycle.
What is the role of pyruvate in glycloysis?
Pyruvate is an end product of glycolysis.
What enzyme converts pyruvate into acetyl-CoA?
Pyruvate dehydrogenase
Which molecule can be made from acetyl CoA molecules?
Pyruvate
What causes the difference between he therotical and actual yields of ATP in aerobic repiration?
ATP is spent transporting pyruvate and ADP into the mitochondrial matrix. Protons leak across the inner mitochondrial membrane without using ATP synthase.
The enzyme pyruvate kinase is responsible for catalyzing the conversion of phosphoenolpyruvate into?
pyruvate
In addition to ATP what are the end products of glycolysis?
NADH and Pyruvate
Is pyruvate a cell?
No, pyruvate is a molecule produced from the breakdown of glucose during glycolysis.
Glycolysis is the breakdown of what organic molecule?
....conversion of glucose to pyruvate.
