Cell Transport

Question 1

Active

Answer 1

requires energy (ATP)

Question 2

Vesicular transport

Answer 2

is the movement of substrates across the cell membrane in membranous bags called vesicles

Question 3

Endocytosis

Answer 3

Is taking liquids or solids into the cell by vesicular transport. This is an active process. The cell membrane folds around a dropplet of liquid or a solid particle. The vesicle so formed then pinches off and is suspended in the cells cytoplasm.

Question 4

Pinocytosis

Answer 4

process during endocytosis when liquids are taken into the cell

Question 5

Phagocytosis

Answer 5

process during endocytosis when the particles taken into the cell contain solid particles

Question 6

Exocytosis

Answer 6

is when the contents of a vesicle inside the cell and passed to the outside

Question 7

Diffusion

Answer 7

the movement of a liquid or gas so that they can be distributed evenly over the available space from a higher concentration to a lower concentration.

Question 8

Osmosis

Answer 8

the diffusion of water molecules through a semi-permeable membrane from an area of higher water concentration to an area of lower water concentration.

Question 9

Passive

Answer 9

doesn’t require energy (ATP)

Question 10

Carrier Mediated

Answer 10

means a carries protein transports specific irons across the membrane

Question 11

Carrier Mediated Facilitated Diffusion

Answer 11

(passive- no energy) -> carrier protein which sucks in/pushes out and causes a change in shape of GLUCOSE

Question 12

Carrier Mediated Active

Answer 12

(required energy + ATP) -> moves from L to H against concentration gradient, this energy from mitochondria and all respiration

Question 13

Simple Diffusion eg

Answer 13

perfume (channel protein)

Question 14

Facilitated diffusion eg

Answer 14

carrier protein - passive (active ATP )
