What major events that occur during Krebs cycle?
Most summaries of the Krebs Cycle will usually indicate that the cycle is an aerobic process (one that requires oxygen) that produces ATP by breaking down glucose.Kreb Cycle shows no oxygen or glucose is used in the cycle and that it does not make much ATP (only one molecule for each acetyl CoA that enters the cycle).
What is the Swanson Conversion?
The Swanson Conversion is another term for Pyruvate Decarboxylation. It is part of the process by which cells produce ATP and takes place before the Krebs Cycle. The origin of the name "the Swanson Conversion" is unknown, but the story goes that there was a high school biology teacher named Swanson who wanted something named after himself, so he told his students to put "the Swanson Conversion" down as another name for pyruvate decarboxylation on its wikipedia page and spread the name around the internet to gain it credibility, and now the name is commonly used as a substitute for "pyruvate carboxylation"
What stage of cellular respiration produces pyruvate as a product?
Pyruvate is produced at the end of glycoysis and converted into Acetyl CoA and then used in tricarboxylic acid (aka Kreb's, citric acid) cycle to ultimately more ATP.
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.
Where does acetyl CoA take place?
Acetyl-CoA is produced during the second step of aerobic cellular respiration. In the matrix of the mitochondria pyruvate decarboxylation occurs.
Is acetyle coenzyme a formed from the breakdown of pyruvic acid?
Precisely, it is called pyruvate decarboxylation. The COOH group Pyruvate is removed as CO2, and Acetyl CoA from Coenzyme A is added in an NAD+ dependent manner by the enzyme decarboxylase.
Which of the following choices is responsible for the decarboxylation in the pyruvate dehydrogenase complex?
Thiamine pyrophosphate (TPP)
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 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.
Glycolysis produces pyruvate. The fate of this pyruvate depends mainly on the availability of which of the following?
Molecular oxygen
What happens immendiately after pyruvate is brought into the mitochondria?
After pyruvate is brought into the mitochondria, it undergoes a series of enzymatic reactions called pyruvate decarboxylation. In this process, pyruvate is converted into acetyl-CoA, which can then enter the citric acid cycle (also known as the Krebs cycle or TCA cycle) to produce energy in the form of ATP.
What stage of cellular respiration pyruvate as a product?
the krebs cycle produces pyruvate as a product to be used by the ATP molecules.

What happens immediately after pyruvate brought into the mitochondrion?
Acetyl CoA forms.
What is the correct sequence of glycolysis electron transfer and Krebs?
Glycolysis->Krebs Cycle->Electron Transfer
