1 Fig. 6-1Figure 6.1 How do cellular components cooperate to help the cell function?
2 Key Cell ConceptsEukaryotic cells have internal membranes that compartmentalize their functionsThe eukaryotic cell′s genetic instructions are housed in the nucleus and carried out by the ribosomesThe endomembrane system regulates protein traffic and performs metabolic functions in the cellMitochondria and chloroplasts change energy from one form to anotherThe cytoskeleton is a network of fibers that organizes structures and activities in the cellExtracellular components and connections between cells help coordinate cellular activities
