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 ...

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.

An unprecedented international effort to decode how cells manage the transport of chemical substances has culminated in four ...

We used 5′ nucleotidase as plasma membrane marker, and glucose-6-phosphatase and thiamine pyrophosphatase as markers for intracellular subfractions. Western- and northern-blot analyses.

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 ...

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 ...

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 ...

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 ...

He is an expert in membrane-based separations ... toward translating nature's sophisticated molecular recognition and transport strategies into robust industrial processes, thus bringing high ...
