Flashcards in Chapter 5 Section 2 Deck (14):
1

the movement of materials up their concentration gradient. From an area of lower concentration to an area of higher concentration. Requires energy.

Active Transport

2

Carrier protein that transports Na+ ions outside the cell and K+ ions up their concentration gradient.

sodium-potassium pump

3

the process by which cells ingest external fluid, macro molecules, and large particles, including other cells.

endocytosis

4

pouch that pinches off from the cell membrane and becomes a membrane bound organelle

vesicle

5

involves the transport of solutes or fluids

pinocytosis

6

the movement of large particles or whole cells

phagocytosis

7

cells that allow lysosomes to fuse with the vesicles that contain the ingested bacteria and viruses.

phagocytes

8

vesicles in the cytoplasm fuse with the cell membrane, releasing their contents into the cell's external environment.

exocytosis

9

cells use exocytosis to release large molecules such as _______

proteins

10

facilitated diffusion carrier proteins and cell membrane pumps both

are specific for the kinds of substances they transport.

11

the sodium-potassium pump transports

Na+ ions out of the cell and K+ ions into the cell

12

the energy needed to power the sodium potassium pump is provided by the

splitting of ATP

13

Pinocytosis involves the transport of

fluids into a cell

14

exocytosis is a

way for cells to release large molecules, such as proteins.
