The short answer: No. Mitochondria are the power-house of the cell. It is where the Electron Transport Chain takes place as well as the production site almost all of the ATP a cell produces. Proteins are produced by ribosomes of the rough endoplasmic reticulum.Okay... the answer above is only partially true.itochondria are the power-house of the cell. It is where the Electron Transport Chain takes place as well as the production site almost all of the ATP a cell produces.
In the mitochondrion, the matrix contains soluble enzymes that catalyze the oxidation of pyruvate and other small organic molecules.The mitochondrial matrix also contains the mitochondria's DNA and ribosomes.The word matrix stems from the fact that this space is viscous, compared to the relatively aqueous cytoplasm. The cytosolic compartment has a water content of 3.8 Î¼l/mg protein, while the mitochondrial matrix 0.8 Î¼l/mg protein.he mitochondrial matrix also contains the mitochondria's DNA and ribosomes.
