Active transport

uses ATP to Move solutes Across a membrane. requires carrier proteins.

symport system

two substances are moved across a membrane in the same direction (active transport)

antiport system

two substances are moved across a membrane in opposite directions (active transport)

primary active transport

hydrolysis of ATP phosphorylates the transport protein causing conformational change.

secondary active transport

use of an exchange pump (such as the na+-k+ pump) indirectly to drive the transport of other solutes

vesicular transport

transport of large particles and macromolecules across plasma membranes

exocytosis

moves substance from the cell interior to the extra cellular space

endocytosis

enables large particles and macromolecules to enter the cell.

transcyotosis

moving substances into, across, and then out of the cell

vasicular trafficking

moving substances from one area in the cell to another

phagocytosis

pseudopods engulf solids and bring them in the cells interior.

fluid-phase endocytosis

the plasma membrane infolds, bringing extracellular fluid and solutes into the interior of the cell

receptors-mediated endocytosis

clathrin-coated pits provide the main route for endocytosis and transcytosis

non-clathrin-coated vesicles

caveolae that are platforms for a variety of signaling molecules.

simple diffusion

uses kinetic energy, (ex.movement of o2 through membrane)

facilitated diffusion

uses kinetic energy; movement of glucose into the cells

osmosis

uses kinetic energy;movement of h2o into and out of the cells

Filtration

Hydrostatic pressure (formation of kidney filtrate)

active transport of solutes

uses ATP; movement of ions across membranes
