People who have McArdie's disease produce less ATP than healthy people. As a result, they are not able to maintain strong muscle contraction during exercise. Use your knowledge of the sliding filament theory to suggest why (AQA BIOL5)
Idea ATP is needed for:1. Attachment / cross bridges between actin and myosin;2. Power stroke / movement of myosin heads in rowing action / pulling of actin towards the centre of the sarcomere;3. Detachment of myosin heads;4. Myosin heads move back to original position / recovery stroke
