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 inner membrane is also loaded with proteins involved in electron transport and ATP synthesis. This membrane surrounds the mitochondrial matrix, where the citric acid cycle produces the electrons that travel from one protein complex to the next in the inner membrane.At the end of this electron transport chain, the final electron acceptor is oxygen, and this ultimately forms water (H20).herefore, power-hungry cells have more mitochondria than cells with lower energy needs. For example, repeatedly stimulating a muscle cell will spur the production of more mitochondria in that cell, to keep up with energy demand.
