Active Membrane Processes

Active Membrane Processes Requires ATP to transport molecules Page 62-64

Active Transport Involves the use of proteins that don’t just passively facilitate the transport of substances across the cell membrane, but requires the use of cellular energy (ATP) to actively pump substances into or out of the cell.

Bulk Transport Requires a vesicle, small membranous sac. to bring the material into the cell.

Exocytosis Exocytosis is the movement of materials out of a cell via membranous vesicles.

Endocytosis Packaging of extracellular materials into a vesicle at the cell surface for importation into the cell.

1. Pinocytosis “Cell Drinking” Formation of small vesicles containing small particles of fluid.

2. Phagocytosis “cell eating” Produces vesicles containing solid large particle objects.
