Which events in muscle contraction require calcium? a. calcium binds to tropomyosin b. calcium binds to troponin c. calcium binds to myosin d. calcium bonds to actin e. more than one of the above

Step 1
Muscle contraction is primarily driven by the interaction between the proteins actin and myosin within the muscle fibers. This process is regulated by two other proteins, troponin and tropomyosin, which are part of the thin filament structure. Show more…

Qudsiya A.
Calcium plays what role in skeletal muscle contraction? a. Binds the myosin head, opening up cross-bridge formation sites on actin b. Binds tropomyosin, causing a conformational change that moves troponin, unblocking the crossbridge formation site on the actin c. Binds globular actin, rolling the tropomyosin from its position, and unblocking the cross-bridge binding site on troponin d. Binds troponin, causing a conformational change that moves tropomyosin, opening up the cross-bridge formation site on the actin molecules
