Question

when at rest, the troponin proteins mask the active myosin binding site on the actin filament"

Answer 1

HERE IS YOUR ANSWER. . . . .

A complex protein Troponin is distributed at regular intervals on the tropomyosin. In the resting state a subunit of troponin masks the active binding sites for myosin on the actin filaments. Each myosin (thick) filament is also a polymerised protein.
