WebCorrect option is A) The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin, exposing the active-binding sites on the actin. ATP then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site. So, the correct option is ' Ca + and Mg++ '. WebExplain the role of muscles in locomotion. Muscle cells are specialized for contraction. Muscles allow for motions such as walking, and they also facilitate bodily processes such as respiration and digestion.
