Question

define sliding filament theory of muscle contraction according to ncert​

Answer 1

Explanation:

The sliding filament theory explains the process of muscle contraction during which the thin filaments slide over the thick filaments, which shortens the myofibril. Each muscle fibre has an alternate light and dark band, which contains a special contractile protein, called actin and myosin respectively.
