Question 3

Anaerobic respiration

Answer 3

the process of releasing energy from glucose, without oxygen.

Question 4

Aerobic exercise

Answer 4

working at a moderate intensity allowing the body time to utilise oxygen for energy production and to work for a continuous period, eg long-distance events.

Question 5

Lactic acid

Answer 5
