    Study Notes

    Golgi Apparatus

    • Stacks of flattened sacs
    • Responsible for packaging and secreting proteins
    • Receives proteins from the endoplasmic reticulum (ER)

    Mitochondria

    • Has two membranes: an outer membrane and an inner membrane
    • The outer membrane is continuous and encloses a central space
    • The inner membrane forms folds called cristae that project into the central space

    Lysosomes

    • Spherical sacs surrounded by a single membrane
    • Contain digestive enzymes
    • Responsible for intracellular digestion
