Which of the Following Generates the Force of Contraction of Skeletal

Question

Which of the following generates the force of contraction of skeletal muscle cells?
A) myosin filaments coil up and shorten
B) sarcomeres coil up and shorten
C) actin cross-bridges bind to myosin and transition from a high-energy to a low-energy state
D) myosin cross-bridges bind to actin and transition from a high-energy to a low-energy state

Accepted Answer

The force of contraction in skeletal muscle cells is generated when myosin cross-bridges bind to actin filaments and transition from a high-energy to a low-energy state, causing the muscle to contract. This process is known as the sliding filament theory.
