Question

Quizplus · Accepted Answer

Actin is the primary protein that makes up the thin filament in skeletal muscle. It forms the backbone of the filament and interacts with myosin to produce muscle contraction. Myosin, on the other hand, is primarily found in the thick filament. Titin is a large protein that spans from the Z-disc to the M-line and helps to maintain muscle elasticity, while Z-discs are proteins that anchor the thin filaments to the sarcomere.
