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.
The electron transport chain and enzymes in the matrix play a large role in the citric acid cycle and oxidative phosphorylation. The citric acid cycle produces NADH and FADH2 through oxidation that will be reduced in oxidative phosphorylation to produce ATP. The cytosolic, intermembrane space, compartment has a water content of 3.8 Î¼l/mg protein, while the mitochondrial matrix 0.8 Î¼l/mg protein.
