    Study Notes

    Golgi Apparatus

    • Found in most eukaryotic cells
    • Proteins synthesized in the ER are packaged into vesicles, which fuse with the Golgi apparatus
    • Proteins are modified and destined for secretion via exocytosis or for use in the cell

    Cytoskeleton

    • System of filaments or fibers present in the cytoplasm of eukaryotic cells
    • Organizes other elements of the cell, maintains cell shape, and responsible for cell locomotion and movement of organelles
    • Complex, dynamic network of interlinking protein filaments from cell nucleus to cell membrane
    • Responsible for maintaining cell shape and movement of cell itself and organelles within it
    • Composed of microtubules, microfilaments, and intermediate filaments

    Microtubules

    • Help maintain cell shape, intracellular transport, and formation of mitotic spindles during mitosis

    Lysosomes

    • Act as waste disposal system of the cell by digesting obsolete or un-used materials
    • Contain more than 60 different enzymes and over 50 membrane proteins
    • Enzymes synthesized in the rough endoplasmic reticulum
    • Found in animal cells and contain variety of enzymes to break down waste materials, old organelles, and foreign invaders

    Vacuoles

    • Membranous sacs that bud from the ER, Golgi, or plasma membrane
    • Come in different sizes and have various functions (food, autophagic, contractile)
    • Found in most protozoan and play roles in digestion and maintaining internal environment

    Nucleus

    • Membrane-bound organelle containing genetic material (DNA) of eukaryotic organisms
    • Largest organelle, facilitates replication, transcription, and translation
    • Maintains integrity of DNA and entire cell volume
    • Controls gene expression and mediates DNA replication during cell cycle
