It depends what type of molecule it is; if it is a water molecule then it moves by Osmosis if it is a gas molecule for example Oxygen then it will move by diffusion.

protein molecules in the cell membrane
Diffusion; a form of passive transport.
Low concentration to high concentration; ATP is used

Active transport moves an object from an area of lower concentration to an area of higher concentration. When the reverse is true, passive transport suffices.
The process is called active transport, and unlike diffusion it uses energy.

The process in which particles move from high to low concentration is called diffusion .
protein molecules in the cell membrane
This process is called diffusion. It is the passive movement of particles from high to low concentration, and is against a concentration gradient. Hope this helps!
