Movement of molecules across the cell membrane
This movement is against the concentration gradient so the transport proteins require an energy supply. Energy is provided by the breakdown of ATP inside the cell. This diagram shows molecules ...
Electrically Controlled Nanogate Revolutionizes Molecular Movement
Scientists at Osaka University have designed a nanogate that opens and closes using electrical signals, offering precise ...

Scientists Destroy 99% of Cancer Cells in Lab With Vibrating Molecules
When in motion, the electrons inside the molecules form what's known as plasmons, collectively vibrating entities that drive ...
A spintronic view of chiral molecules: Physicists verify chiral-induced spin selectivity effect
The role of electrons and their negative charge in electric current is well established. Electrons also exhibit other ...

Transport across membranes Diffusion
Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules.
