The flashcards below were created by user ChapinJeanie on FreezingBlue Flashcards. What would you like to do?


  1. Cytosol
    • Viscous semitransparent fluid
    •    *water, nutrients, waste, ions, whatever makes the cell work
  2. Organelles
    • Little organs
    •  *each with a specific function
  3. Inclusions
    stored substances
  4. Organelles (Membranous and non_membranous)
     
    Mitochondria
    • Powerhouse of the cell
    • provides most of the ATP
    •   *many per cell
    •   * double membrane
    •   * contains own dna therefor can replicate itself
    •    * contains enzymes  glycolysis TCA KRELPS, electon transport
  5. Organelles (Memebranous and non membranous)

    Ribosomes
    • protein factories
    •    * NO membrane
    •    *float free and attach to membranes
    •    *two subunits 1 small 1 large
    •     *stringy wadded piece of DNA
  6. Organelles (Membraneous and non membraneous)

    Endoplasmic reticulum (ER)
    • sac like network of membranes
    •    *Endo-in
    •    *Plasmic - plasma
    •    *reti-membrane
    •     * culum-network
    •   RER deals like protien sythesis, export.
  7. Organelles (membraneous and non)

    Rough Endoplasmic Recticulm
    • RER, protien is an export 
    •    *makes protien
  8. Organelles (membraneous and non)

    Smooth endoplasmic recticulum
    • SER
    • doesn't make protiens
    • lipid  sythesis
    • no ribosomes
  9. Organelles (membraneous and non)

    Golgi
    • a flattended stack of sac like membranes
    •  Processes proteins from the ER
    • Forms the secretory vesticles for ptotein export
  10. Organelles (membraneous and non)

    Lysossomes
    • "suicide pack" of cells
    • contains enzymes "ase"
  11. Organelles (membraneous and non)


    Cytoskeleton
    Structural internal and external protein support
  12. Organelles (membraneous and non)
    Cytoskeleton

    Microtubules
    • hollow protien tubes
    •    * moves things around cell
    •    * part of cell division
    •    * look like straw
  13. Organelles (membraneous and non)
    Cytoskeleton

    Microfilaments
    • thin strands of protein
    •   *found in muscle cells
  14. Organelles (membraneous and non)
    Cytoskeleton

    Intermediate filaments
    • tough proteins
    •    *makes skin tough
  15. Organelles (membraneous and non)

    Centrioles
    • made of microtubules
    •   * near nucleus
    •   * aid in cell division
    •   *move DNA around
  16. Cellular extensions formed of microtubles
     

    Cilia
    • hair like extensions that moves things
    •    * move things around
    •    * direction of the cilli dictate direction of movement 
    •    * EX trachea, oviduct
  17. Cellular extensions formed of microtubules


    Flagella
    • only found in sperm cells
    •    *the microtubule tail
