This is a document mainly for students taking AQA Additional Science. It contains information on respiration (both aerobic and anaerobic) as well as exercise and our body from the B3 (biology) specification. I hope this helps you to revise! Please rate and comment on how to improve :) Also, i have a study group called AQA Additional Science where we discuss topics such as this one and many more. Feel free to become a member, the more the merrier!
