Where in the cell is pyruvate broken down?
Pyruvate is broken down in the mitochondria of the cell through a process called aerobic respiration. Pyruvate is converted into acetyl-CoA, which then enters the citric acid cycle to produce ATP, the cell's main energy source.
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.
Does oxidation of pyruvate need oxygen to occur?
Yes.In a cell the only pathway that oxidizes pyruvate is the series of reactions in the mitochondria that lead eventually to complete oxidation to carbon dioxide and water. This process requires oxygen as a final acceptor of the hydrogen atoms removed during this oxidation.The complete pathway involves the link reaction and the reactions of the Krebs (citric acid) cycle.
What are the 4 main stages of cellular respiration and where do they take place in a eukaryotic cell?
The 4 main stages of cellular respiration are glycolysis (in the cytoplasm), pyruvate oxidation (in the mitochondria), the citric acid cycle or Krebs cycle (in the mitochondria), and oxidative phosphorylation (in the inner mitochondrial membrane).
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.
What is the exact location of pyruvate oxidation in the mitochondrion?
Pyruvate oxidation takes place in the mitochondrial matrix. Here, pyruvate is converted into acetyl-CoA by the pyruvate dehydrogenase complex, which is a critical step in aerobic respiration.
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.
Is Co2 released during oxidation of pyruvate to acetyl CoA?
Yes, during the oxidation of pyruvate to acetyl CoA in the mitochondria, CO2 is released through decarboxylation reactions. This process is part of the pyruvate dehydrogenase complex, where pyruvate is converted to acetyl CoA, releasing CO2 as a byproduct.
Where in the cell is pyruvate broken down?
Pyruvate is broken down in the mitochondria of the cell through a process called aerobic respiration. Pyruvate is converted into acetyl-CoA, which then enters the citric acid cycle to produce ATP, the cell's main energy source.
Where is oxidation of pyruvate located?
The oxidation of pyruvate occurs in the mitochondria of eukaryotic cells. This process is part of cellular respiration and generates acetyl CoA, which then enters the citric acid cycle to produce ATP.
What are the products of pyruvate oxidation?
acetyle-CoA NADH CO2 hydrogen ion
Where is pyruvate oxidation in bacteria?
I have the same question. I also need to know which microbe contains the enzyme phospoenolyruvate carboxylase. I am doing a project on this, and I need some answers. I guess we're in this together. :)
Which of the following is not a possible fate of the glucose which is taken into cells?
Oxidation to pyruvate via gluconeogenesis
What process occurs before the Krebs cycle?
The formation of acetyl-CoA

Does pyruvate oxidation occur in the cytoplasm?
Pyruvate is broken down oxidized to CO2 in the mitochondria. The oxidation of pyruvate also reduces coenzymes NADH and FADH2. The electrons from these coenzymes are fed through the electron transport chain and eventually end up on oxygen creating water. The transport of electrons through the ETC pumps protons (H+) from the mitochondrial matrix to the inner membrane space. This creates a proton gradient that forces protons back through an integral membrane protein in the inner mitochondrial membrane called ATP Synthase. The rotation of ATP Synthase creates ATP from ADP and Pi.
What is the purpose of glycolysis?
To make 2ATP 1 NAD+ and 2 pyruvate.
