Cell Membrane

Question 1

Carbohydrate chain attached to the phospholipid

Answer 1

Glycolipid

Question 2

Carbohydrate chain attached to a protein

Answer 2

Glycoprotein

Question 3

Stabilize and give shape to the membrane

Answer 3

Peripheral protein

Question 4

The carrier protein. Moves side to side

Answer 4

Integral protein

Question 5

What is the function of the cell membrane

Answer 5

It’s the gateway to the cell. Allows needed things in and wastes out

Question 6

What are the 5 types of proteins

Answer 6

Channel, carrier, cell recognition, receptor, and enzymatic protein

Question 7

Function of channel protein

Answer 7

Allows a particular molecule or ion to cross the plasma membrane freely

Question 8

Function of carrier protein

Answer 8

“carry” the ion or molecule across the membrane by changing shape after the binding of the ion or molecule. Carrier proteins are involved in passive and active transport.

Question 9

Function of cell recognition protein

Answer 9

proteins that are embedded in the cellular membrane that allow cells to communicate with each other.

Question 10

Function of receptor protein

Answer 10

Is shaped in such a way that a specific molecules combine to it

Question 11

Function of enzymatic protein

Answer 11

Catalyzes a specific reaction. The membrane protein, adenylate cyclase, is involved in ATP metabolism

Question 12

What is diffusion

Answer 12

the movement of particles from an area of higher concentration to lower concentration.

Question 13

What is osmosis

Answer 13

the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution

Question 14

What are the 3 ways of increasing the rate of diffusion

Answer 14

Increase temp, increase the concentration gradient, and decrease the size of the diffusing molecules

Question 15

Solute

Answer 15

Substance that is being dissolved in solvant

Question 16

Solvent

Answer 16

A fluid which is used to dissolve a solute

Question 17

Solution

Answer 17

A homogeneous mixture created when solutes are dissolved in a solvent

Question 18

Osmotic pressure

Answer 18

The pressure due to the flow of water from the area of greater concentration to the area of lesser concentration

Question 19

Equilibrium

Answer 19

When osmotic pressure equals hydrostatic pressure

Question 20

Animal cell placed in hypo solution

Answer 20

Cell swells. Lysis

Question 21

Animal cell in hyper solution

Answer 21

Cell shrinks. Crenation

Question 22

Plant cell in hypo solution

Answer 22

Greater water pressure inside cell. Turgor pressure

Question 23

Plant cell and hyper solution

Answer 23

Cell content shrink but cell wall remains in shape (wilted plant cell) plasmolysis

Question 24

Facilitated transport

Answer 24

The process of spontaneous passive transport of molecules or ions across a biological membrane. Uses carrier or channel proteins. Does not need ATP

Question 25

Active transport

Answer 25

the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration

Question 26

Endocytosis and exocytosis

Answer 26

Another way to get molecules. Especially large particles, in and out of cell

Question 27

Endocytosis

Answer 27

Cell membrane forms a vesicle around the substance to be taken in

Question 28

The three vesicles of endocytosis

Answer 28

Phagocytosis, pinocytosis, and receptor-meditated endocytosis

Question 29

What molecules need diffusion to pass through cell membrane

Answer 29

highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
