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.
Mitochondrial matrix also consists of a wide variety of enzymes for kreb s cycle, amino acid metabolism, protein metabolism, nucleic acid metabolism and fatty acid oxidation. Mitochondrial DNA found in the matrix is found in multiple copies from 40 to 60 or more.itochondrial matrix is also involved in citric acid cycle, where energy rich co-enzymes like FADH2 and NADH2 are produced. They are then taken up by cristae membranes, where they are step wisely and sequentially oxidized. During this process, the energy released is used for the synthesis of ATP.
