이 집합의 용어 (15)

  • Cytoskeleton
    An organized, dynamic network of protein filaments providing structural support, shape, and adaptability within the cell.
  • Intermediate Filaments
    Protein structures offering tensile strength, protecting the nucleus and maintaining cell shape under mechanical stress.
  • Microtubules
    Hollow protein cylinders forming internal frameworks, enabling transport, cell division, and movement via cilia and flagella.
  • Actin Filaments
    Thin protein strands lining the plasma membrane, crucial for maintaining and altering cell shape during movement.
  • Microfilaments
    Alternative name for actin filaments, emphasizing their fine, thread-like structure near the cell's periphery.
  • Protein Filaments
    Linear polymers of proteins forming the structural basis of the cytoskeleton, assembled from repeating subunits.
  • Monomers
    Small, individual protein subunits that join to form larger cytoskeletal filaments through non-covalent interactions.
  • Non-covalent Bonds
    Weak chemical interactions allowing rapid assembly and disassembly of cytoskeletal structures for cellular flexibility.
  • Protofilament
    A linear chain of joined monomers, serving as the basic building block for larger cytoskeletal structures.
  • Helical Lattice
    A twisted arrangement of multiple protofilaments, resembling a rope, enhancing filament strength and stability.
  • Nucleation
    The energy-dependent initial assembly of a few monomers, creating a foundation for rapid filament growth.
  • Plasma Membrane
    The cell's outer boundary, closely associated with actin filaments that help maintain and modify cell shape.
  • Cilia
    Microtubule-based projections enabling cell movement or the movement of substances along the cell surface.
  • Flagella
    Long, whip-like microtubule structures specialized for propelling certain cells through fluid environments.
  • Tensile Strength
    The resistance to being pulled apart, provided by intermediate filaments to protect cellular and nuclear integrity.
