WebActin and myosin are both proteins, which puts them in the [1] level of organization. Calcium ions are also important in the muscular system, because the presence of calcium ions triggers the actin and myosin interaction that leads to a contraction. Calcium ions are at the smallest level of organization, which is this level: [2]. WebBest Videos, Notes & Tests for your Most Important Exams.
