Paper 1 - Aerobic and anaerobic respiration

Question 1

Aerobic respiration

Answer 1

-this happens when exercising for long periods of time.
-the training zone is 60-80% of you maximum heart rate.
-used for low to high intensity activities.
-glucose + oxygen = energy + carbon dioxide + water

Question 2

Anaerobic respiration

Answer 2

-this happens when exercising at full effort for short periods (e.g. 60 seconds or less).
-the training zone is 80-90% of maximum heart rate.
-used for medium to high intensity activities.
-this type of respiration does not use oxygen for energy.
-glucose is broken down without oxygen.
-glucose = energy + lactic acid
