    Study Notes

    Intracellular Transport

    • The primary function of intracellular transport within a cell is to distribute proteins and other molecules to their respective organelles.
    • In eukaryotic cells, proteins are distributed to their respective organelles through a process of vesicle trafficking, where proteins are packaged into vesicles and transported to their target organelles.
    • Vesicles are trafficked between organelles and the plasma membrane with the help of motor proteins, which play a vital role in this process.
    • What is unique to eukaryotic cells in terms of intracellular transport is the use of vesicle-mediated transport to distribute proteins and other molecules to their respective organelles.
    • Packets of components are transported to particular intracellular locations in eukaryotic cells through the use of vesicles, which are formed by invagination of the Golgi apparatus.

    Tensile Structures

    • Tensile structures carry axial loads, which are forces that are applied along the length of the structure.
    • Cables and tubes combine both tension and compression elements to form a stable structure.
    • The most common type of thin-shell structures is the dome.
    • Most tensile structures are supported by cables and masts.
    • The most common use of tensile membrane structures is to provide roofing for large public spaces, such as stadiums and event centers.
