Here, a transport vesicle from the Golgi or elsewhere in the cell merges its membrane with the plasma membrane and releases its contents. In this way, membranes are continually recycled and reused ...

Nearly all the molecules that are expressed in mammalian cells reach their correct intracellular locations by virtue of sophisticated transport-and-delivery systems. Central among these is the ...

Membrane transport proteins are specific and selective ... In contrast to prokaryotes, eukaryotic cells have not only a plasma membrane that encases the entire cell, but also intracellular ...

are translocated to the plasma membrane through fusion of the storage vesicles. 70 There is a precedent for defective transport and translocation of GLUT-4 as a cause of insulin resistance ...

Seed plants, such as soybeans, store large amounts of protein in specialized organelles called protein storage vacuoles.

For example, sodium ions are transported across the plasma membrane, and the electrochemical gradient powers active transport of another ion or molecule. Hydrogen pumps build up an electrochemical ...

Substances are recycled back to the plasma membrane by transport vesicles that bud off from the endosomal tubular domains. Endosomes play active roles in many important physiological processes.

A general concept in biology is that cells use two different systems to transport substances across their membrane: selective pores, which allow passive transport driven by a concentration ...

Ion-transport membranes are vital components of ... This trade-off presents a challenge in developing membrane materials that meet the required performance criteria. In a study published in ...

"We expect that this membrane will be useful for rejection of substances like boron that are not easy to reject with current desalination membranes," says Karnik. Water transport across the nanopores ...
