Transport Across the Plasma Membrane

Require ATP to get work done

Do not require the cell to expend energy because the kinetic energy of the particles causes them to move from an area of high concentration to an area of low concentration

Movement of molecules or ions by kinetic energy from their greater concentration to their lesser concentration until equilibrium is reached

Movement of water molecules by diffusion across a selectively permeable membrane, movement is from a hypotonic solution into a hypertonic solution, water moves until equilibrium is reached

Movement of a substance down its concentration gradient using a transmembrane protein for support

Flow of liquid through the pores of a filter or plasma membrane, movement due to hydrostatic pressure

Movement of a substance against its concentration gradient using a transmembrane protein and ATP for transport

Movement of substance in to or out of a cell using vesicles that form at or fuse with plasma membrane

Movement of substances into a cell via vesicles forming at the plasma membrane

A type of endocytosis, specialized movement of solid particles into cell by pseudopodia forming a vesicle around the particles, "cell eating"

A type of endocytosis, drops of fluid brought into a cell by invagination of the plasma membrane forming a small vesicle, "cell drinking"

Movement of substances out of a cell via fusion of secretory vesicles with the plasma membrane
