- 1What level must Ca2+ reach to bind to the troponin complex?>5 micro moles
- 2Which part of the troponin complex does Ca2+ bind to?Troponin C
- 3What happens once Ca2+ has bound?Troponin I pulls the tropomyosin away from the actin
- 4Once the tropomyosin pulls away from the actin...The myosin head can bind to it
- 5ADP is released from the head and...ATP replaces it
- 6Once ATP binds,...The head releases the actin
- 7ATP is hydrolysed to ADP & Pi, and....The myosin head undergoes a conformational change
- 8Once hydrolysis occurs...The myosin head weakly rebinds
- 9When the Pi is released...A powerstroke occurs
- 10What happens in the power stroke?The myosin head returns to its original conformation pulling the actin with it
