C) ATP molecules.
In a resting muscle fibre, troponin partially covers
Ca ++ ions are then pumped back into the SR, through the process of active transport, which requires ATP. The lack of Ca ++ ions causes the tropomyosin to reshield (or re-cover) the binding sites on the actin strands, allowing the actin (thin) and myosin (thick) interaction to relax, ending the cross-bridge cycle. This leads to the muscle

When a muscle is in a resting state, actin and myosin are separated. To keep actin from binding to the active site on myosin, regulatory proteins block the molecular binding sites. Tropomyosin blocks myosin binding sites on actin molecules, preventing cross-bridge formation and preventing contraction in a muscle without nervous input.

At Rest Active Sites On The Actin Are Blocked By
When a muscle is in a resting state, actin and myosin are separated. To keep actin from binding to the active site on myosin, regulatory proteins block the molecular binding sites. Tropomyosin blocks myosin binding sites on actin molecules, preventing cross-bridge formation and preventing contraction in a muscle without nervous input.
When Ca 2+ is released in response to the change in voltage, it binds to actin, causing actin filaments to shift position and revealing myosin binding sites for the cross-bridges. The muscle contracts until the nerve impulse stops and Ca 2+ returns to its storage sites.
