|
FILTRATION |
movement of water and solutes through a selectively permeable membrane as a result of HYDROSTATIC PRESSURE |
|
|
SIMPLE DIFFUSION |
diffusion of particles through water or air or through a living or artificial membrane, DOWN THEIR CONCENTRATION GRADIENT, WITHOUT AID OF MEMBRANE CARRIERS |
|
|
OSMOSIS |
net flow of water through a selectively permeable membrane, driven by either a DIFFERENCE IN SOLUTE CONCENTRATION or a MECHANICAL FORCE |
|
|
FACILITATED DIFFUSION |
transport of particles through a selectively permeable membrane, DOWN THEIR CONCENTRATION GRADIENT, by a CARRIER THAT DOES NOT DIRECTLY CONSUME ATP |
|
|
ACTIVE TRANSPORT |
transport of particles through a selectively permeable membrane, UP THEIR CONCENTRATION GRADIENT, with the aid of a CARRIED THAT CONSUMES ATP |
|
|
PRIMARY ACTIVE TRANSPORT |
DIRECT TRANSPORT of solute particles by an ATP-USING MEMBRANE PUMP |
|
|
SECONDARY ACTIVE TRANSPORT |
transport of solute particles by a CARRIER THAT DOES NOT IN ITSELF USE ATP, but depends on concentration gradients PRODUCED by PRIMARY ACTIVE TRANSPORT |
|
|
COTRANSPORT |
transport of 2 OR MORE solutes SIMULTANEOUSLY in the SAME DIRECTION through a membrane by either FACILITATED DIFFUSION OR ACTIVE TRANSPORT |
|
|
COUNTERTRANSPORT |
transport of 2 OR MORE DIFFERENT solutes in OPPOSITE DIRECTIONS through a membrane by either FACILITATED DIFFUSION OR ACTIVE TRANSPORT |
|
|
UNIPORT |
carrier that transports ONLY ONE SOLUTE, using either FACILITATED DIFFUSION OR ACTIVE TRANSPORT |
|
|
SYMPORT |
carrier that PERFORMS COTRANSPORT |
|
|
ANTIPORT |
carrier that PERFORMS COUNTERTRANSPORT |
|
|
ENDOCYTOSIS |
vesicular transport of particles INTO A CELL |
|
|
PHAGOCYTOSIS |
process of ENGULFING LARGE PARTICLES by means of PSEUDOPODS, "CELL-EATING" |
|
|
PINOCYTOSIS |
process of IMBIBING EXTRACELLULAR FLUID in which the plasm membrane SINKS IN and PINCHES OFF small vesicles containing droplets of fluid |
|
|
RECEPTOR-MEDIATED ENDOCYTOSIS |
PHAGOCYTOSIS or PINOCYTOSIS in which SPECIFIC SOLUTE particles BIND to receptors on the plasma membrane, and are then TAKEN INTO THE CELL in CLATHRIN-COATED vesicles with a MINIMAL amount of EXTRANEOUS MATTER |
|
|
EXOCYTOSIS |
process of ELIMINATING material from a cell by means of a vesicle approaching the cell surface, FUSING with the plasma membrane, and expelling its contents; used to release cell secretions, replace worn-out plasma membranes and replace membrane that has been internalized by endocytosis |
