Unit 2 Concept 2 - CELL TRAVEL

Question 1

Passive Transport

Answer 1

requires no extra energy by the cells
because molecules move from high concentration (squished together) to low concentration (spread out) areas down the concentration gradient

Question 2

Active Transport

Answer 2

Requires extra energy (ATP) to be spent to bring materials into the cell or expel materials out of the cell moving from low to high concentration against the concentration gradient.

Question 3

Solute

Answer 3

what gets dissolved

Question 4

Solvent

Answer 4

what does the dissolving

Question 5

Solution

Answer 5

uniform mixture

Question 6

Concentration

Answer 6

Amount of solute dissolved in solvent

Question 7

Concentration Gradient

Answer 7

Difference in concentration of a substance from one location to another

Question 8

Simple diffusion

Answer 8

the spreading out of molecules across a membrane until equilibrium is reached.

Question 9

Equilibrium

Answer 9

equally concentrated on both sides of the membrane`

Question 10

What transport transports 02 and C02,

Answer 10

simple

Question 11

Facilitated diffusion

Answer 11

transport proteins,
helps to facilitate the diffusion of molecules that normally couldn’t pass through the cell membrane.

Question 12

Osmosis

Answer 12

: the simple diffusion of water across the cell membrane.

Question 13

What transports large molecules like calcium

Answer 13

facilitated

Question 14

Hypotonic solutions

Answer 14

water concentration is higher than the cells cytoplasm

Question 15

if a solution is hypotonic to a hypertonic cell then the cell will _____

Answer 15

if a solution is hypotonic to a hypertonic cell then the cell will swell

Question 16

Hypertonic Solution

Answer 16

Hypertonic is when water concentration is lower than the cell cytoplasm

Question 17

if a solution is hypertonic to a hypotonic cell, then the cell will ____.

Answer 17

if a solution is hypertonic to a hypotonic cell, then the cell will shrivel.

Question 18

Isotonic

Answer 18

is identical water concentration to cells cytoplasm.

Question 19

Molecular pump

Answer 19

uses energy to pump molecules across the membrane against the concentration gradient
through a protein pannel

Question 20

what transports charged ions

Answer 20

molecular pumps

Question 21

Endocytosis:

Answer 21

uses vesicles to move large particles into the cell

Question 22

what are the 2 types of endocytosis

Answer 22

phagocytosis or pinocytosis

Question 23

Phagocytosis

Answer 23

cell eating, cell engulfs solids into vesicles and and digests them

Question 24

Pinocytosis

Answer 24

cell drinking, cell engulfs liquid into vesicles and and digests them

Question 25

Exocytosis

Answer 25

uses vesicles go export materials out of the cell

Question 26

Example of exocytosis

Answer 26

when nerve cells use neurotransmitters to send signals throughout the body
