Transport of molecules within a cell and out of the cell requires a complex endomembrane system. Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell ...

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

Their ports of entry are sophisticated transport channels embedded in a cell's protective membrane. Regulating what kinds of cargo can pass through the borderlands formed by the cell's two-layer ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

Researchers from the Göttingen Cluster of Excellence Multiscale Bioimaging (MBExC) have uncovered the 3D structure of the ...

The oxygen diffuses across the partially permeable membrane of the alveoli cells and the capillary wall, into the red blood cells to be carried around the body. Osmosis close osmosisThe movement ...

Membrane proteins are key targets ... of better understanding how these proteins transport certain substances into and out of the cell. This method also has the advantage of being easily ...

Important membrane transport mechanism in pathogenic bacteria Date: January 8, 2024 Source: Universitatsklinikum Bonn Summary: Some bacterial membrane transporters work almost like freight ...

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 ...

We don’t know much about the regulation of endocytosis and cell-to-cell transport in the muco-ciliary epithelium of the upper respiratory tract. Viruses, on the other hand, know all about it. We use ...
