Cellular Transport and Homestatsis
-
the movements of molecules or particles from an area of high concentration to an area of low concentration
diffusion
-
this is the process of carrying materials out of a cell using vesicles
Exocytsis
-
this refers to the movement of water across a semi permeable membrane
facilitated diffusion
-
this type of transport moves substances against the concentration gradient and requires energy
active
-
this is the process of carrying materials into a cell using vesicles
endocytosis
-
this type of transport moves substances with the concentrations gradient and does not require energy
passive
-
this type of transport occurs when specialized proteins help increase the rate at which a particle moves across a semi permeable membrane. it does not require energy.
