5.3 ANAEROBIC RESPIRATION

Question 1

What is the equation for anaerobic respiration?

Answer 1

Glucose -> (energy^) lactic acid
Glucose is broken down by lactic acid to release energy

Question 2

What are the disadvantages of anaerobic respiration?

Answer 2

1. Toxicity of lactic acid
2. Low efficiency of energy production

Question 3

Where does anaerobic respiration happen in?

Answer 3

Cytoplasm

Question 4

What are some examples of anaerobic respiration exercise?

Answer 4

1. Sprinting
2. Push up

Question 5

When is anaerobic respiration important?

Answer 5

1. During low oxygen supply (e.g. high intensity exercises)
2. For bacteria living in low oxygen environments (e.g. soil, deep sea)
3. During alcoholic fermentation

Question 6

Does anaerobic respiration require oxygen?

Answer 6

No

Question 7

What does anaerobic respiration produce?

Answer 7

Lactic acid

Question 8

What is the main type of respiration used in sprinting races?

Answer 8

Anaerobic respiration

Question 9

Which type of respiration produces short bursts of energy?

Answer 9

Anaerobic respiration

Question 10

Although anaerobic respiration produces 2 energy, it is _____ than ________________

Answer 10

faster ; aerobic respiration

Question 11

Why can’t anaerobic respiration be used all the time?

Answer 11

Anaerobic respiration produces lactic acid, and lactic acid is toxic

Question 12

Why can anaerobic respiration produce a sudden burst of energy even though it only releases a small percentage of the energy in each glucose molecule?

Answer 12

Incomplete glucose breakdown
