TRANSPORT METHODS Flashcards
passive transport , carrier mediated transport , bulk transport
the three methods of membrane transport
Simple Diffusion , Osmosis
two types of passive transport
Facilitated transport , Active transport
two types of carrier mediated transport
uniport system , symport system , antiport system
they are the three types of active transport
endocytosis , exocytosis
the two types of bulk transport
Phagocytosis , Pinocytosis , Receptor Mediated Endocytosis
they are the three types of endocytosis
in general does not require energy , substances move from an area of higher concentration to an area of lower concentration , does not require a transporter .
passive transport
what kind of transport occur when , substances move from an area of higher concentration to an area of lower concentration ,
simple diffusion transport
water molecules diffuse through a selectively permeable or semipermeable membrane from areas of high water concentration ( low solute concentration ) to areas of lower water concentration( high solute concentration ) .
osmosis
diffusion of water across a membrane term
osmosis
Higher solute in solution then in a cell , Water moves out of the cell
Hypertonic tonicity
Equal amounts of solute , Water moves Into and out of cell at the same time .
Isotonic tonicity
Lower solute in solution than in cell , Water moves Into the cell .
hypotonic tonicity
substances pass into the cell with a transporter
( special protein , as channel proteins and carrier proteins ) .
carrier mediate transport
the pass of substances from the area of low concentration to the area of high concentration with a transporter carrier protein .
facilitated transport of a carrier mediated transport
moving the substances from the area of low concentration to the area of high concentration with a transporter carrier protein , require energy
active transport
moving just one substance from the area of low concentration to the area of high concentration with a transporter carrier protein , require energy
uniport system of the active transport
moving one or more substance across the membrane , from the area of low concentration to the area of high concentration with a transporter carrier protein , on one direction .
symport system of the active transport
moving one substance or more across the membrane from the area of low concentration to the area of high concentration with a transporter carrier protein , on two opposite directions .
antiport system of the active transport
the moving of molecules of or large fluids across the membrane in vesicles .
bulk transport
when the cell eat solid substance
phagocytosis of endocytosis bulk transport
occurs in few specialized cells such as neutrophils
phagocytosis of endocytosis , bulk transport
when the cell drink liquid substances
pinocytosis of endocytosis , bulk transport
the endocytosis that occur in all cells of human body
pinocytosis of endocytosis , bulk transport
when substances bind to receptor sites then pass across the membrane in a vesicle called endosome
receptor mediate endocytosis - endocytic vesicles
the discharge of material from vesicles at the cell surface
exocytosis , bulk transport
