Actin is thin, pulled together by myosin.

What are the myofilaments called in a muscle cell?

The myofilaments in a muscle cell are called actin and myosin. Actin and myosin are protein filaments that work together during muscle contraction to generate force and movement.


Describe the process that cause the muscle to contract?

# When the muscle is in a resting state, thin strands of a protein called tropomyosin are wrapped around the actin filaments, blocking the myosin binding sites. This keeps the myosin from binding to actin. # Molecules called troponin are attached to the tropomyosin. # When calcium is introduced into the muscle cell, calcium ions bind to troponin molecules. # Calcium then pulls troponin, causing tropomyosin to be moved as well, therefore causing the myosin binding sites on the actin to be exposed. # Myosin binds to the now-exposed binding sites. # As soon as the myosin head binds to actin, the head bends at its hinge. # Once the head bends, the myosin loses energy, and remains attached to the actin. # When re-energized by adenosine triphosphate (ATP), the myosin head detaches from the actin filament, and is ready to attach and bend again. # The collective bending of numerous myosin heads (all in the same direction), combine to move the actin molecules closer together. This results in a muscle contraction.

What myofilament does the pulling?

The myosin myofilament pulls on the actin myofilament during muscle contraction. This interaction, known as the sliding filament theory, results in the shortening of the sarcomere and muscle contraction.


What protein has cross-bridge heads that pull on the thin fiber?

The protein responsible for the cross-bridge mechanism that pulls on the thin filament is myosin. In muscle contraction, myosin heads attach to binding sites on the actin filaments (the thin fibers) and pull them closer together, which shortens the muscle fiber. This process is driven by the hydrolysis of ATP, providing the energy necessary for contraction. The interaction between myosin and actin is fundamental to muscle movement and contraction.

What 2 molecules are part of actin?

The two main molecules that make up actin are globular actin (G-actin) and filamentous actin (F-actin). G-actin is the monomeric form of actin, while F-actin is the polymeric form that results from the polymerization of G-actin subunits.
