aerobic respiration

Question 1

Aerobic

Answer 1

Respiration that requires oxygen, this gives out more energy than anaerobic respiration

Question 2

Enzymes

Answer 2

Control chemical reactions inside cells

Question 3

Mitochondria

Answer 3

Most of the reactions in aerobic respiration take
place inside here

Question 4

Aerobic respiration equation

Answer 4

C6H12O6 + 6O2 > 6CO2 + 6H2O

Question 5

Suggest an explanation for why plants need to respire continuously. ( 2 marks)

Answer 5

Any 2 from
- plants cannot use energy from sunlight directly for metabolic processes
- so they need energy from respiration for this purpose
- during the day as well as at night

Question 6

Aerobic and anaerobic respiration can happen in muscle cells. Compare these two processes. ( 4 marks)

Answer 6

Any four from
- both use glucose/release energy
- aerobic respiration produces carbon dioxide/water but anaerobic respiration does not
- aerobic respiration releases more energy than anaerobic respiration
- aerobic respiration needs oxygen but anaerobic respiration does not

Question 7

Give one advantage and disadvantage of Aerobic respiration. ( 2 marks)

Answer 7

Advantage - releases more energy than anaerobic respiration
Disadvantage - needs oxygen/produces carbon dioxide
