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.

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 ...

Endosomal recycling is a branch of intracellular membrane trafficking that retrieves endocytosed cargo proteins from early and late endosomes to prevent their degradatio ...

Lipid bilayer forms a water-impermeable barrier that defines the boundary of a cell and of specialized compartments within a cell ... Zhou’s lab focuses on two families of proteins, membrane transport ...

This membrane protects the cell from its surroundings and divides it into internal compartments; it is responsible for metabolism, energy production, communication with other cells and much more.
