Hope this helps you
Answer:
Conversion of pyruvate to acetyl coA take place in the matrix of mitondondrial.
Electron transport chain occur in the inner mitochondrial membrane of the cell.
Breakdown of glucose to pyruvate occur in the cytoplasm of the cell.
Citric acid cycle occur in the matrix of the mitondondrial.
Explanation:
Cellular respiration refers to the processes that take place in the cell which breakdown glucose to give energy.
In the eukaryotic cells, conversion of pyruvate to acetyl coA occur in the matrix of the mitondondrial. The pyruvate from glycolysis move into the mitondondrial, the site of cellular respiration and it is converted to acetyl coA.
The electron transport chain occur in the inner of mitondondrial in the eukaryotic cells which is the site where oxidative phosphorylation occur through the activity of enzyme ATP synthase.
The breakdown of glucose to pyruvate , called glycolysis occur in the cytoplasm of the cell. It require no oxygen. Glycolysis is the process that lead to conversion of glucose to pyruvate.
Citric acid cycle take place in the matrix of mitondondrial and it a process where energy is produced from oxidation of acetyl coA into carbondioxide. It is also called Krebs cycle.

Here are the 3 parts of the cell theory:
1. Cells are the basic building blocks of any living things.
2. Any living thing is composed of more than 2 cells.
3. New cella arise from the old
