Explain the sliding filament theory. What are the roles of myosin, actin, Z lines, and other components in this process?
- Myosin and actin push each other apart, causing muscle relaxation
- Myosin and actin form a gel that stabilizes the muscle
- Actin pulls on myosin, causing Z lines to move farther apart
- Myosin pulls on actin, causing Z lines to move closer together
