Transpot notes


Diffusion The movement of molecules from an area of high concentration of that type of molecule, to an area of low concentration of that type of molecule, without using energy, until equilibrium is reached.
Osmosis The diffusion of water across an selectively permeable membrane.
Active Transport (Transport that requires energy. Therefore it must be done by a cell. It is the opposite of diffusion.) It is when molecules move from and area of low concentration to an area of high concentration. Using energy. The Equilibrium is never reached.
Endocytosis When particles that are to large to pass through the pores in the cell membrane entering the cell using cell energy.
Exocytosis When particles that are too large to move through pores in the cell membrane exiting the cell, using energy
Selectively permeable membrane It allows some things in to the cell while keeping other things in or out.
