Used to create membrane potential in animal cells Vacuoles are responsible for a wide variety of important functions in a cell including nutrient storage, detoxification, and waste exportation. Vacuoles and lysosomes also participate in programmed cell death. The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
