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.
No, pyruvate oxidation does not occur in the cytoplasm. It takes place in the mitochondria. Pyruvate produced in the cytoplasm during glycolysis is transported into the mitochondria for oxidation to acetyl-CoA.
No, pyruvate is a molecule that produced at the end of the glycolytic cycle
No, it occurs exclusively in the mitochondrial matrix in eukaryotes.
Pyruvate is synthesized in cytoplasm.It is turned into Acetyle Co A and transported into matrix.

Where does the breakdown of pyruvate occur?
Cytoplasm
Where does glcolysis in cells occur?
Glycolysis occurs in the cytoplasm of cells. It is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process.
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.
Where is pyruvate metabolized?
pyruvate is converted into acetyl coA in the mitochondrial matrix
Where does the breakdown of glucose during respiration occurs?
The breakdown of glucose during respiration occurs in the cytoplasm and mitochondria of cells. In the cytoplasm, glycolysis breaks down glucose into pyruvate. Pyruvate then enters the mitochondria where the citric acid cycle and oxidative phosphorylation occur to further break down glucose and produce ATP.
Where does the breakdown of pyruvate occur?
Cytoplasm
Where does the synthesis of pyruvate occur during glycolysis?
The synthesis of pyruvate occurs in the cytoplasm of the cell during glycolysis. It is the final step in the glycolytic pathway, where glucose is converted to two molecules of pyruvate.
Where is pyruvate oxidation in bacteria?
Pyruvate oxidation in bacteria occurs in the cytoplasm of the cell. Pyruvate is converted into acetyl-CoA by the enzyme pyruvate dehydrogenase complex, which then enters the TCA cycle in the bacterial cell's cytoplasm or mitochondria.
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 in a eukaryotic cell do the reactions of glycolysis occur?
The reactions of glycolysis occur in the cytoplasm of a eukaryotic cell. The enzymes required for glycolysis are found in the cytoplasm, where glucose is broken down into pyruvate to produce energy in the form of ATP.
Where does glcolysis in cells occur?
Glycolysis occurs in the cytoplasm of cells. It is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process.
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.
Where is pyruvate metabolized?
pyruvate is converted into acetyl coA in the mitochondrial matrix
Where in cell is pyruvate broken down?
cytoplasm
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.
Where does the breakdown of glucose during respiration occurs?
The breakdown of glucose during respiration occurs in the cytoplasm and mitochondria of cells. In the cytoplasm, glycolysis breaks down glucose into pyruvate. Pyruvate then enters the mitochondria where the citric acid cycle and oxidative phosphorylation occur to further break down glucose and produce ATP.
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).
