Which are products of pyruvate dehydrogenase?
Pyruvate dehydrogenase complex react with pyruvate to form acetyl-CoA
Which enzyme is the most similar to Pyruvate dehyrogenase a citrate dyhydrogenase b malate dehydrogenase c succinate dehydrogenase d isocitrate dehydrogenase e alpha ketoglutarage dehydrogenase?
alpha-ketoglutarate dehydrogenase is most similar to pyruvate dehydrogenase as both are enzyme complexes made of 3 units
What enzyme is responsible for aerobic respiration?
There are very many enzymes involved. A few from glycolysis are: hexokinase and glucokinase, phosphohexose isomerase, phosphofructokinase, pyruvate kinase; from pyruvate decarboxylation are pyruvate dehydrogenase phosphatase and pyruvate dehydrogenase kinase; and a few from the Kreb's cycle are: aconitase, alpha-ketoglutamate dehydrogenase, succinate thiokinase, and fumarase.
Where is pyruvate dehydrogenase complex located in prokaryotes?
in cyptoplasm of the prokaryotic cell
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 enzyme converts pyruvate into acetyl-CoA?
Pyruvate dehydrogenase
What is the function of dehydrogenase?
dehydrogenase is an enzyme which transfers hydrogen ions from a substrate to an activator.Example are activators are NAD+ and FAD+.

In what phase of cellular respiration is not ATP produced?
Pyruvate dehydrogenase complex

Which of the following are true about lactate dehydrogenase?
Correct answer: I, II, III and IV
What vitamins are required for operation of the pyruvate dehydrogenase enzyme complex?
Thiamin, niacin, and riboflavin
Which of the following choices is responsible for the decarboxylation in the pyruvate dehydrogenase complex?
Thiamine pyrophosphate (TPP)

What happens after pyruvate is brought into the mitochondrion?
It is carried by specific transporters (the negative charge on pyruvate won't allow it to diffuse) before being acted on by pyruvate dehydrogenase. I don't think these transports are named.
