Question

The sliding filament model of contraction states that __________. the sliding filament model of contraction states that __________. during contraction, the thin myofilaments slide past the thick myofilaments so that the actin and myosin myofilaments overlap to a greater degree during contraction, the thin myofilaments slide past the thick myofilaments so that the actin and myosin myofilaments no longer overlap during contraction, the thin myofilaments slide past t tubules so that the z discs are overlapping during contraction, the thin myofilaments slide past the thick myofilaments so that calcium ions can be released from the sarcoplasmic reticulum submit

Answer 1

I believe that sliding filament model of contraction states that; during contraction, the thin filaments slide past the thick filaments so that actin and myosin filaments overlap. According to this model the myosin or thick filaments of muscle fibers slide past the actin or thin filaments during muscle contraction, while the two groups of filaments remain at relatively constant length.
