Cell Membrane

Question 1

Diffusion

Answer 1

The movement of gas molecules that move directly across the cell membrane

Question 2

Osmosis

Answer 2

The movement of water molecules that moves directly through the cell membrane

Question 3

Facilitated diffusion

Answer 3

The movement of larger molecules through the protein channel

Question 4

Phospholipid bilayer

Answer 4

Consists of two layers of phospholipid with a hydrophobic(tails,fear of water/repelling and hydrophilic(heads,attracting water)

Question 5

Active transport

Answer 5

The movement of substances from lower concentration to higher concentration by the use of energy

Question 6

Passive transport

Answer 6

Movement of substance from high concentration to low concentration with using energy

Question 7

Semi permeable

Answer 7

A membrane that will allow certain molecules or ions to pass through it by diffusion

Question 8

Concentration gradient

Answer 8

Occurs when the concentration of particles is higher in one area than another

Question 9

Endocytosis

Answer 9

A process by which cells absorb external material by engulfing it with the cell membrane

Question 10

Exocytosis

Answer 10

The movement of materials out of the cell

Question 11

Isotonic

Answer 11

Any external solution that’s has the same solute concentration and water concentration compared to body fluids

Question 12

Hypotonic

Answer 12

When the outside of a cell has more water and even it out by transporting water to the cell

Question 13

Hypertonic

Answer 13

When the cell has more water than the outside of the cell and transports water to the outside of the cell

Question 14

Phospholipid

Answer 14

Major membrane lipids that consist of lipid bilayers

Question 15

Solute

Answer 15

The mirror component in a solution, dissolved in the solvent

Question 16

Solution

Answer 16

A liquid mixture in which mirror component is uniformly distributed within the major components

Question 17

Solvent

Answer 17

Any substance, usually liquid , which is capable of dissolving one or several substances, thus creating a solution

Question 18

Hydrophobic

Answer 18

Fear of water or repelling

Question 19

Hydrophilic

Answer 19

Attracting of water

Question 20

Cholesterol

Answer 20

Helps to stabilize the structure of the cell membrane

Question 21

Protein channel

Answer 21

Transports specific molecules across the membrane

Question 22

Glycoproteins

Answer 22

Cell surface markers identify cell to other cells by carbohydrates attached

Question 23

Tails

Answer 23

Repels, polar molecules, sugars, proteins ions, and cell wastes

Question 24

Heads

Answer 24

Attracts water by hydrogen bonds
