Transport across membranes

Question 1

Simple Diffusion

Answer 1

the passive movement of molecules from areas of high concentration to areas of low concentration(down the concentration gradient)

Question 2

Facilitated diffusion

Answer 2

passive transport where molecules move through a phospholipid bilayer with the aid of a membrane protein

Question 3

Osmosis

Answer 3

passive transport of a solvent(typically water) through a semipermeable membrane from a region of low solute to a region of high solute

Question 4

Active transport

Answer 4

movement of molecules across a semipermeable membranes that require energy

Question 5

Bulk Transport - Exocytosis

Answer 5

moves large substances out of the cell

Question 6

bulk endocytosis

Answer 6

moves large substances into a cell

Question 7

hypertonic

Answer 7

a solution with a higher solute concentration when compared to another solution

Question 8

isotonic

Answer 8

a solution with the same solute concentration as another solution

Question 9

hypotonic

Answer 9

a solution with a lower solute concentration when compared to another solution

Question 10

passive transport

Answer 10

the movement of molecules through a semipermeable membrane and down the concentration gradient without an input of energy

Question 11

extracellular

Answer 11

outside the cell

Question 12

intracellular

Answer 12

inside the cell

Question 13

solute

Answer 13

a substance dissolved in solvent

Question 14

solution

Answer 14

a liquid in which a solute is dissolved, forming a solution
