ACTIVE TRANSPORT

Question 1

solute

Answer 1

something that dissolves in something else

Question 2

solvent

Answer 2

substance in which a solute is dissolved

Question 3

concentration

Answer 3

the amount of solute per unit of solvent

Question 4

diffusion

Answer 4

the movement of material across the cell membrane from a region of high concentration to a region of low concentration

Question 5

active transport

Answer 5

the movement of material across the cell membrane against the concentration gradient

Question 6

how is AT carried out

Answer 6

transport proteins that are embedded in the cell membrane use ATP to move substances against the concentration gradient

Question 7

cytosis

Answer 7

a transport mechanism responsible for the transport of molecules in and out of the cell

Question 8

2 types of cytosis

Answer 8

Endo and Exo

Question 9

Endocytosis

Answer 9

movement of large materials into the cell

part of the cell membrane wraps around the particle and engulfs it

Question 10

types of endocytosis

Answer 10

phagocytosis

pinocytosis

Question 11

phagocytosis

Answer 11

particles taken into the cell

Question 12

pinocytosis

Answer 12

liquids taken into the cell

Question 13

exocytosis

Answer 13

movement of large materials out of the cell

vesicles form around the particle
the vesicles combine with the cell membrane
the particle is then expelled from the cell
