Sample Question 1
Define Exchange Surface.

A basic surface with no adaptations for facilitating molecule movement.

An exchange surface is a specialised area that is adapted to make it easier for molecules to cross from one side of the surface to the other.

An area that blocks molecules from crossing from one side to the other.

A surface that remains static and does not allow any movement of molecules.

Sample Question 2
What substances are essential for living cells? (6)

Sodium for energy production

- oxygen for aerobic respiration- glucose as a source of energy - proteins for growth and repair- fats to make membranes and to be a store of energy- water- minerals to maintain their water potential and to help enzyme action and other aspects of metabolism

Carbon dioxide for respiration

Vitamin C for cell communication

Sample Question 3
What characteristics do effective exchange surfaces share?

- large surface area to provide more space for molecules to pass through- thin barrier to reduce diffusion distance- fresh supply of molecules on one side to keep the concentration high- removal of required molecules on the other side to keep the concentration low

- lack of fresh supply of molecules which decreases concentration levels

- small surface area which limits the space for molecules to pass through

- thick barrier which increases diffusion distance
