In the electron transport chain, NADH-Q reductase, succinate, ubiquinone, cyochrome c reductase, and cytochrome c oxidase are proteins embedded in the inner membrane of the mitochondria. Also embedded is ATP synthase, an enzyme--a specialized protein.
The electron transport chain is located in the cristae of a mitochondria. It is the enzymes used during the Krebs cycle that are found in the matrix of the mitochondria. In plants, the electron transport chain is located in the thylakoid membrane of a chlorophyll.
Mitochondria are located in the tail of the sperm. They provide the sperm with that whip like energy to move. They can give the energy to the sperm because mitochondria are the "powerhouse" of the cell.
No. Mitochondria are the cell's powerhouses. The cytoplasm is the part of the cell that is enclosed within the cell membrane. A cell's mitochondria are located within the cytoplasm along with the rest of the cell's components, for example the nucleus.
