5 Which of the following is not true with respect to vertebrate skeletal muscle? 1. Calcium ions are released into the muscle fibre’s cytosol from sarcoplasmic reticulum 2. The ‘A-band’ within a sarcomere represents the length of myosin myofilaments 3. Muscle fibre force production is independent of sarcomere length 4. After the effect of a muscle fibre action potential ends Ca 2+ is actively transported out of the cytosol 5. In the ‘power stroke’ the actin filaments are moved towards the centre of a sarcomere
