Flashcards in Chapter 5 Section 2 Deck (14)
the movement of materials up their concentration gradient. From an area of lower concentration to an area of higher concentration. Requires energy.
Carrier protein that transports Na+ ions outside the cell and K+ ions up their concentration gradient.
the process by which cells ingest external fluid, macro molecules, and large particles, including other cells.
pouch that pinches off from the cell membrane and becomes a membrane bound organelle
involves the transport of solutes or fluids
the movement of large particles or whole cells
cells that allow lysosomes to fuse with the vesicles that contain the ingested bacteria and viruses.
vesicles in the cytoplasm fuse with the cell membrane, releasing their contents into the cell's external environment.
cells use exocytosis to release large molecules such as _______
facilitated diffusion carrier proteins and cell membrane pumps both
are specific for the kinds of substances they transport.
the sodium-potassium pump transports
Na+ ions out of the cell and K+ ions into the cell
the energy needed to power the sodium potassium pump is provided by the
splitting of ATP
Pinocytosis involves the transport of
fluids into a cell
