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
