Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. (10) 7. (sliding filament mechanism) BLANK is twisted helix, containing tropomyosin and troponin. (5) Down 2. (sliding filament mechanism) BLANK is molecule shaped like golf club, twisted tail, head pointed outwards. (6) 3. Calcium floods into the muscle cell binding with troponin allowing actin and myosin to bind. The actin and myosin cross bridges bind and contract using ATP as energy. This is muscle BLANK (11) 4. The motor nerve stimulates an action potential (impulse) to pass down a neuron to the neuromuscular junction. This stimulates the sarcoplasmic reticulum to release calcium into the muscle cell. This is muscle BLANK (10) 5. Anna is working very hard which makes her very BLANK (6) 6. ATP is re-synthesised allowing actin and myosin to maintain their strong binding state. This is muscle ....
