Answer
oxygen
Explanation
Aerobic respiration is a type of respiration that relies on oxygen to produce energy. However, if our muscles are working hard ( such as during vigorous exercise ) and they aren’t getting oxygen as they would like, then they start to respire without (an-) oxygen (aerobically). This process can briefly provide the energy muscles need to continue functioning, albeit not quite as efficiently as aerobic respiration.
