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

Question

Quizplus · 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.
