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.

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 ...

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 recent study by Chinese scientists has revealed the intricate molecular machinery driving energy exchange within ...

Botanists have come to understand the channels and transporters involved in the uptake and transport of nutrients, yet how are they positioned where they need to be? For example, plants need boron ...
