  2. Intracellular transport - Wikipedia

    en.wikipedia.org/wiki/Intracellular_transport

    Intracellular transport is more specialized than diffusion; it is a multifaceted process which utilizes transport vesicles. Transport vesicles are small structures within the cell consisting of a fluid enclosed by a lipid bilayer that hold cargo. These vesicles will typically execute cargo loading and vesicle budding, vesicle transport, the ...

  3. COPI - Wikipedia

    en.wikipedia.org/wiki/COPI

    Electron micrograph of in vitro–formed COPI-coated vesicles. Average vesicle diameter at the membrane level is 60 nm. COPI is a coatomer, a protein complex [1] that coats vesicles transporting proteins from the cis end of the Golgi complex back to the rough endoplasmic reticulum (ER), where they were originally synthesized, and between Golgi compartments.

  4. Vesicular transport adaptor protein - Wikipedia

    en.wikipedia.org/wiki/Vesicular_transport...

    Vesicular transport adaptor proteins are proteins involved in forming complexes that function in the trafficking of molecules from one subcellular location to another. [2] [3] [4] These complexes concentrate the correct cargo molecules in vesicles that bud or extrude off of one organelle and travel to another location, where the cargo is ...

  5. Cisterna - Wikipedia

    en.wikipedia.org/wiki/Cisterna

    The first step in the secretory pathway is the formation of transport vesicles at the ER. These vesicles are coated with COPII, a protein complex essential for budding from the ER. COPII coats consist of the small GTP-binding protein Sar1 and two additional complexes: Sec23/Sec24 and Sec13/Sec31. These coat proteins interact with membrane cargo ...

  6. Facilitated diffusion - Wikipedia

    en.wikipedia.org/wiki/Facilitated_diffusion

    Facilitated diffusion in cell membrane, showing ion channels and carrier proteins. Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins. [1]

    That solution would take current Air National Guard units — nine of them, in six different states — and move them to the U.S. Space Force. The proposal is not without controversy.

  8. Vesicle (biology and chemistry) - Wikipedia

    en.wikipedia.org/wiki/Vesicle_(biology_and...

    Vesicles can also fuse with other organelles within the cell. A vesicle released from the cell is known as an extracellular vesicle. Vesicles perform a variety of functions. Because it is separated from the cytosol, the inside of the vesicle can be made to be different from the cytosolic environment. For this reason, vesicles are a basic tool ...
