A research team has revealed the molecular steps that led to the emergence of this plant-specific vacuolar transport system. Their work shows that the acquisition of this pathway was driven by the ...

The passage of these molecules relies on specific transport proteins embedded in the membrane. Membrane transport proteins are specific and selective for the molecules they move, and they often ...

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 ...

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 ...

Zhu Ying from Beihang University. "Our membrane not only enhances proton transport efficiency but also opens the door to converting industrial waste acid into electricity." This study highlights a ...

The net movement of water from a region of high water concentration to a region of low water concentration through a selectively permeable membrane. This means osmosis is a special case of ...

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 ...
