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.
Keywords: mitochondrial; ribosomal proteins; oxidative phosphorylation; candidate genes; translation. Most of the energy requirements for cell growth, differentiation, and development are met by the mitochondrial ATP produced by the process of oxidative phosphorylation.utations (or absence) of ribosome assembly proteins or other essential proteins, such as MRPL12, may be lethal due to the absence or inadequate amounts of functional mitochondrial ribosomes. MRPL12 is the initial binding site for elongation factors on the mitochondrial ribosome.
