substrate and what do they break them down into?
1)
2)
How do they work? (explain & draw
the lock & key mechanism
3)

Describe the effects that exercise has on the body. For each
effect, explain why this happens
Aerobic Respiration
Explain the term ‘oxygen debt’
Anaerobic respiration
Give three reasons with detail as to
why organisms need to respire
How do you repay this debt?
