5.4 Active Transport

Question 1

Active transport

Answer 1

Particles moving at a rate faster than the rate of diffusion, stopping an equilibrium. Energy-requiring process

Question 2

Selective transport

Answer 2

Membrane determines what molecules are able to go in and out of the cell

Question 3

Bulk transport

Answer 3

Form of active transport, two types; endocytosis and exocytosis

Question 4

Phagocytosis

Answer 4

Type of endocytosis, used for moving solids. Membrane enfolds material, forming a vesicle. Vesicle pinches off and moves into cytoplasm

Question 5

Pinocytosis

Answer 5

Type of endocytosis, used for liquids. Membrane enfolds material, forming a vesicle. Vesicle pinches off and moves into cytoplasm

Question 6

Exocytosis

Answer 6

Reverse of endocytosis. Vesicles, usually formed by Golgi Apparatus, moves towards and fuse with cell surface membrane, contents are then released
