7.

How does respiration differ from breathing?

a)

Respiration involves the exchange of gases in the lungs.

b)

Breathing is the process of cellular energy production.

c)

Breathing and respiration are the same physiological process.

d)

c)

Mitochondria are responsible for photosynthesis in plants.

d)

Mitochondria store oxygen for cellular respiration.

9.

What is aerobic respiration?

a)

Aerobic respiration is a type of fermentation process.

b)

Aerobic respiration is the process of producing cellular energy in the presence of oxygen.

c)

Anaerobic respiration occurs without oxygen.

d)

Aerobic respiration is the breakdown of glucose without energy production.

10.

What is anaerobic respiration and when does it occur?

a)

Anaerobic respiration occurs only in plants.

b)

Anaerobic respiration requires high levels of oxygen.

c)

Anaerobic respiration is the same as aerobic respiration.

d)

Anaerobic respiration occurs when oxygen is not available.
