What does "A" represent on the diagram?

A) Myosin myofilament
B) Actin myofilament
C) Sarcomere
D) Z disk
E) Cross-bridge

Z Disk

A structure within a muscle's sarcomere that serves as the attachment point for thin filaments, critical for muscle contraction.

Actin Myofilament

Actin myofilaments are the thin filaments in muscle cells that, along with myosin, play a crucial role in muscle contraction.

Myosin Myofilament

A type of protein filament in muscle cells responsible for the contractile properties of muscles.

  • Achieve insight into the molecular aspects of muscle contraction, including the involvement of calcium and designated enzymes.
