2 Student Learning Outcomes: Describe the four interacting systems of eukaryotic cells. Trace the possible fates of a lipid molecule from its origin to either the nuclear envelope or plasma membrane. Differentiate between targeting signals found in proteins with various cellular localizations. Explain the endosymbiotic theory and how it resulted in semiautonomous organelles.
