Study Notes
Bulk or Vesicular Transport
- Bulk transport is how large molecules, unable to be carried by transport proteins, move into and out of a cell.
- Eggs, milk, and meat are rich sources of proteins which aid in muscle, immune system, bone development and metabolism.
- Proteins are essential macromolecules for crucial cellular functions.
- Proteins and other large molecules are transported via bulk or vesicular transport.
- Bulk transport involves multiple steps: budding, scission, uncoating, translocation, tethering, and fusion.
- The processes can be remembered using the acronym BSUTTF.
- Vesicles are structures within or outside the cell, containing cytoplasm enclosed by a lipid bilayer.
- Vesicles are created during processes of secretion, uptake and transport of molecules.
- Golgi bodies frequently produce vesicles that transport cell products to the cell membrane.
- The general mechanism of Bulk transport includes a series of steps: budding, scission, uncoating, translocation, tethering, and fusion.
- Coat proteins bind to sorting signals.
- Molecules are transported using a vesicle around a liquid molecule during pinocytosis.
- Phagocytosis involves the cell engulfing molecules through extensions.
- Exocytosis releases molecules outside the cell and endocytosis transports molecules into the cell.
- Cell transport types include exocytosis, phagocytosis, pinocytosis and receptor-mediated endocytosis.
