14. Which of these statements about breathing is incorrect?
A
Gases easily pass across the wall of the alveoli because they are thin
B
The blood vessels next to the alveoli have thick walls to prevent oxygen escaping
C
Emphysema victims have difficulty breathing because the damaged alveoli have less surface area
D
Gas exchange in the lungs is very efficient because of the large surface area of the alveoli

Your breathing rate is lower during exercise
B
Respiration produces oxygen gas
C
Carbon monoxide is a waste product of respiration
D
Breathing out uses energy
19. Bacteria do not have mitochondria. Can they still respire?
A
No, because all respiration happens in the mitochondria
B
Yes, because they still have the enzymes needed for respiration
C
No, because they do not have the surface area needed for respiration
D
Yes, because bacteria respire in the nucleus
