  2. Passive transport - Wikipedia

    en.wikipedia.org/wiki/Passive_transport

    Passive diffusion across a cell membrane.. Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. [1] [2] Instead of using cellular energy, like active transport, [3] passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.

  3. Kraken (Cercozoa) - Wikipedia

    en.wikipedia.org/wiki/Kraken_(Cercozoa)

    The cell body can also move along a deeply branched filopodia. In a unique manner, Kraken can also completely disassemble its cell body and transport cell material through the filopodia network, where it is then deposited and reassembled elsewhere. This serves to move the cell body to the distal ends of the filopodia, which can then reposition ...

  4. Transcellular transport - Wikipedia

    en.wikipedia.org/wiki/Transcellular_transport

    Passive transport is the process of moving molecules from an area of high concentration to an area of low concentration without expelling any energy. There are two types of passive transport, passive diffusion and facilitated diffusion .

  5. 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]

  6. Uniporter - Wikipedia

    en.wikipedia.org/wiki/Uniporter

    Mechanism of uniport transport across cell membrane. Uniporters work to transport molecules or ions by passive transport across a cell membrane down its concentration gradient. Upon binding and recognition of a specific substrate molecule on one side of the uniporter membrane, a conformational change is triggered in the transporter protein. [27]

  9. Membrane transport - Wikipedia

    en.wikipedia.org/wiki/Membrane_transport

    As mentioned above, passive diffusion is a spontaneous phenomenon that increases the entropy of a system and decreases the free energy. [5] The transport process is influenced by the characteristics of the transport substance and the nature of the bilayer. The diffusion velocity of a pure phospholipid membrane will depend on: concentration ...
