Question 0

Diffusion

Answer 0

Movement of molecules or ions by kinetic energy from their greater to lesser concentration.

Question 1

Passive process and examples

Answer 1

Do not use ATP

Ex. Diffusion, osmosis, facilitated diffusion, filtration.

Question 2

Osmosis

Answer 2

Movement of water molecules by diffusion across a selective permeable membrane. Moves from hypo tonic to hypertonic, move until equilibrium is reached.

Question 3

Facilitated diffusion

Answer 3

Movement of a substance down its concentration gradient using a transmembrane protein for transport.

Question 4

Filtration

Answer 4

Flow of liquid through the pores of a filter or plasma membrane.

Question 5

Active processes and examples

Answer 5

Cell uses ATP to move substances across the plasma membrane.

Ex. Active transport, vesicular transport, endocytosis, phagocytosis, pinocytosis, exocytosis.

Question 6

Active transport

Answer 6

Movement of a substance against its concentration gradient using a transmembrane protein and ATP.

Question 7

Vesicular transport

Answer 7

Movement of a substance in to or out of a cell using vesicles that form or fuse with the plasma membrane.

Question 8

Endocytosis

Answer 8

Movement of substances into a cell via vesicles forming at the plasma membrane.

Question 9

Phagocytosis

Answer 9

A type of endocytosis; specialized movement of solid particles into a cell by pseudo podia forming a vesicle around the particles “cell eating”

Question 10

Pinocytosis

Answer 10

A type of endocytosis; drops of fluid brought into a cell by invagination of the palms membrane forming a small vesicle “cell drinking”
