cell transport (alc)

Question 1

requires no energy, HIGH to LOW concentration

Answer 1

simple diffusion

Question 2

a passive process, no energy is used to make the molecules move, natural KINETIC ENERGY

Answer 2

diffusion

Question 3

solute moves DOWN the concentration gradient, (HIGH to LOW)

Answer 3

diffusion through membrane

Question 4

diffusion of water across a membrane

Answer 4

osmosis

Question 5

moves from HIGH water concentration to LOW water concentration

Answer 5

osmosis

Question 6

water is attracted to solute (salt), it travels to areas of low solute concentration to high solute concentration

Answer 6

osmosis

Question 7

high water concentration ——–> low water concentration

low solute concentration ——> high solute concentration

Answer 7

diffusion of water across a membrane

Question 8

a solution whose solute concentration is the same as the solute concentration inside the cell

Answer 8

isotonic

Question 9

a solution whose solute concentration is lower than the solute concentration inside the cell

Answer 9

hypotonic

Question 10

a solution whose solute concentration is higher than the solute concentration inside the cell

Answer 10

hypertonic

Question 11

cell is at equilibrium, water flows in both directions

Answer 11

isotonic

Question 12

water is going inside the cell

Answer 12

hypotonic

Question 13

water is going out the cell

Answer 13

hypertonic

Question 14

cytolysis

Answer 14

hypotonic

Question 15

plasmolysis

Answer 15

hypertonic

Question 16

destruction of the cell, causes cell to swell and burst

Answer 16

cytolysis

Question 17

the shrinking of a cell, causes cell to shrink and shrivel

Answer 17

plasmolysis

Question 18

doesn’t require energy, moves high to low

Answer 18

passive transport: simple diffusion

Question 19

doesn’t require energy, uses transport proteins to move high to low

Answer 19

passive transport: facilitated diffusion

Question 20

molecules with randomly move through the pores in Channel Proteins

Answer 20

facilitated diffusion

Question 21

2 types of transport proteins

Answer 21

channel proteins and carrier proteins

Question 22

embedded in cell membrane and have pore for materials to cross

Answer 22

channel proteins

Question 23

change shape to move material from one side of the membrane to the other

Answer 23

carrier proteins

Question 24

some carrier proteins don’t extend through the membrane

Answer 24

facilitated diffusion

Question 25

requires energy or ATP, moves from low to high, against concentration gradient

Answer 25

active transport

Question 26

3 Na+ pumped in for every 2 K+ pumped out; creates a membrane potential

Answer 26

sodium-potassium pump

Question 27

molecule are moved out of the cell by vesicles that fuse with the plasma membrane

Answer 27

active transport- exocytosis

Question 28

large molecule move materials into the cell by pinocytosis, receptor-mediated endocytosis, or phagocytosis

Answer 28

active transport- endocytosis

Question 29

most common form of endocytosis, takes in dissolved molecules as a vesicle

Answer 29

active transport- pinocytosis

Question 30

some integral proteins have receptors on their surface to recognize and take in hormones, cholesterol, etc.

Answer 30

receptor-mediated endocytosis

Question 31

used to engulf large particles such as food, bacteria, etc. into vesicles

Answer 31

active transport- phagocytosis
