Q. No.The sliding filament theory of muscle contraction proposes that:
1. Actin filaments slide past myosin filaments causing sarcomere shortening during contraction
2. Myosin filaments slide past actin filaments causing sarcomere elongation during contraction
3. Both actin and myosin filaments shorten simultaneously during muscle contraction
4. Z-lines move closer by contraction of actin and myosin filaments themselves
