Explain the sliding filament hypothesis for muscle contraction and relaxation

Answer 1

Explain sliding hypothesis for relaxation. muscle construction and → The mechanism of this theory that of constraction binding of myosin to actin forming cross-bridge, that generate silament movement * The sliding silament theory explain that how these cross - bridge are formed and the subseque nt contraction of muscle. For contraction occurs there must birst be stimulate the muscle in form of action potential from a motor neuron - The individual motor neleron plug muscle tibers it. stimulate called motor unit the neuromuscular junction of motor neuron abon and the muscle. biber are stimulate -muscle tiber of motor unit stimulate the reantion in sarcomere between actin, and myosin tilament. That rean steests with contraction and sliding Bilament theory : - Troponin is complex of three that protein integral to muscle contraction that attached to protein tropomy osin within actin bilament. - when thuscle is relaxed tropomyosin blocks with attachement site of myosin cross bridge, thus preventing construction.
