Asymmetric

Question 11

Property of a cell membrane that allows it to control which molecules can pass through it.

Answer 11

Selective Permeability

Question 12

they are different in terms of array of phospholipids and proteins that form in a membrane.

Answer 12

Selective Permeability

Question 13

Some proteins serve to anchor the membrane to fibers of the cytoskeleton.

Answer 13

Interior

Question 14

Composed of peripheral proteins that bind elements of the ECM.

Answer 14

Exterior

Question 15

These help the cell bind substances that the cell needs in the extracellular fluid.

Answer 15

Carbohydrates

Question 16

This adds considerably to the selective nature of the plasma membrane.

Question 17

This characteristic helps the movement of some materials through the membrane and hinders the movement of others.

Answer 17

Amphiphilic

Question 18

What happens when the cell membrane loses its selectivity?

Answer 18

The cell cannot sustain itself and would be destroyed. The cell must have a way of obtaining these materials of the ECM.

Question 26

It does not require energy but needs a membrane transport channel or carrier protein to transport ions such as Na & K.

Answer 26

Facilitated Diffusion

Question 27

Polar molecules and large ions dissolve in water and are passively and specifically transport across the membrane.

Answer 27

Facilitated Diffusion
