Question 15

Substances can move in and out of the cell through the membrane using a method called…

Answer 15

Diffusion.

Question 16

Define diffusion

Answer 16

The spreading of particles from an area of high concentration, to a lower concentration.

Question 17

Diffusion occurs spontaneously due to…

Answer 17

The random movement of fluid particles(kinetic energy).

Question 18

The greater difference in concentration…

Answer 18

The faster the rate of diffusion.

Question 19

Why does a greater concentration difference mean the rate of diffusion is higher?

Answer 19

There’s a steeper concentration gradient.

Question 20

Why can amino acids diffuse through a cell membrane but proteins can’t?

Answer 20

Because the amino acids are relatively small molecules and proteins are too large.

Question 21

How does oxygen, used for respiration, pass through the cell membrane?

Answer 21

Diffusion.

Question 22

If there’s a difference in concentration, anything dissolved in a solution……diffuse.

Answer 22

CAN diffuse.
