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