The fоllоwing steps оf muscle contrаction аre listed but аre NOT in the correct order. A. Calcium ions are released from the sarcoplasmic reticulum B. Acetylcholine is released into synaptic cleft C. Impulse travels along sarcolemma of a muscle cell and down T tubules D. Tropomyosin slides over to expose binding sites on the thin filaments E. Sarcomere shortens and the muscle contracts AB. Nerve impulse travels down the motor neuron and reaches synaptic terminal AC. Calcium binds to troponin AD. Acetylcholine attaches to receptors on the sarcolemma AE. Cross bridges form between actin and myosin Which of the above steps occurs second?
