Cell membrane, ribosomes, DNA, and cytoplasm

Question 19

Phospholipid head is…

Answer 19

Polar and Hydrophilic

Question 20

Phospholipid tail is…

Answer 20

Nonpolar and Hydrophobic

Question 21

When the membrane only lets certain things in and out

Answer 21

Semipermeable or selectively permeable

Question 22

Examples of small things that are permeable

Answer 22

O2, CO2

Question 23

Examples of large things that are impermeable

Answer 23

Glucose, macros

Question 24

Difference between Passive and Active Transport

Answer 24

Passive: Doesn’t need ATP, high -> low
Active: Needs ATP, low -> high

Question 25

When water moves to be equal on both sides of the membrane

Answer 25

Dynamic equilibrium

Question 26

Three main types of Passive Transport

Answer 26

Diffusion, Facilitated Diffusion, and Osmosis

Question 27

Facilitated diffusion is…

Answer 27

When things use protein channels in the membrane to diffuse

Question 28

The movement of WATER in the membrane

Answer 28

Osmosis

Question 29

Protein channels specifically for water

Answer 29

Aquaporins

Question 30

Difference between Isotonic, Hypertonic, and Hypotonic

Answer 30

Isotonic: equal on both sides
Hypertonic: cell shrivels up because water is higher inside, lower outside
Hypotonic: Cell bursts because water is higher outside, lower inside

Question 31

Plants have this to keep them from bursting with water

Answer 31

Osmotic Pressure

Question 32

Two main types of Active Transport

Answer 32

Protein pumps and Endo/Exocytosis

Question 33

Active transport that uses membrane proteins

Answer 33

Protein pumps

Question 34

Endo/Exo cytosis

Answer 34

Endo: things come in and get “eaten”
Exo: things exit, excrete waste

Question 35

Endocytosis for solids vs liquids

Answer 35

Solids: phagocytosis
Liquids: pinocytosis
