Cells (Plasma Membrane (Types of membrane transport (Endocytosis-…

- - - - Materials move across the plasma membrane from areas of high concentration to areas of lower concentration
    - - Materials move from areas of higher concentration to areas of lower concentration through a protein channel
    - - Materials move from areas of lower concentration to areas of higher concentration through a protein channel, uses ATP to move against the gradient
    - - Piinocytosis
        
        Nonselective
        
        Cell creates a vesicle, takes in a small amount of extracellular material, and the vesicle closes off
      - Receptor mediated endocytosis
        
        Selective- protein receptors only take in specific substances
        
        Cell creates a vesicle, takes in a small amount of select extracellular material, and closes off
    - - Large molecules, entire dying cells or invaders are entirely engulfed by another cell
    - - Opposite of endocytosis
      - Material is enclosed in a vesicle within the cell and the cell opens the vesicle to release it
- - - - Stucture- Dense particles, free or attached to endoplasmic reiticulum
      - Function- Protein synthesis
    - - Structure- Membrane system studded with ribosomes
      - Function- Protein synthesis, plasma membrane synthesis
    - - Structure- membranous system
      - Function- Lipid synthesis and metabolism and some hormone synthesis
    - - Structure- membranous system
      - Function- Receives protein from RER, sorts, modifies and repackages protein
    - - Structure- Membranous sac of enzymes
      - Function- Breaks down biological substances- debris
    - - Structure- Membranous sac of enzymes
      - Function- Breaks down toxic substances
    - - Structure- Double membrane structure
      - Function- Site of ATP synthesis
    - - Structure- Fine filaments of contractile protein actine
      - Function- Involved in cellular movement
      - Not permanent- Build up and break down
    - - Structure- Protein fibers larger than microfilaments
      - Function- Resists tension (pulling) forces acting on cell
    - - Structure- Hollow cylindrical structure
      - Function- Highways for movement of cell components, supports the cell, gives it shape, involved in cellular movement, forms centrioles
      - Not permanent- build up and break down
    - - Structure- Paired cylindrical bodies composed of microtubules
      - Function- Involved in process of cell division, from base of cilia and flagella
