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 ...

Lysosomes are membrane-bound organelles in cells that act as recycling centers—breaking down waste materials, damaged ...

Professor ZHANG Zhen’s team at the Suzhou Institute for Advanced Research, University of Science and Technology of China ...

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 ...

A research team from the Qingdao Institute of Bioenergy and Bioprocess Technology of the Chinese Academy of Sciences, along with collaborators, has ...

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 ...
