03. Mechanism of Muscle Contraction
Locomotion and Movement

238298 The contraction of the muscle continues in sliding filament theory

1 Till ATP binds to myosin head
2 Till ADP binds to myosin head
3 Till \(\mathrm{Ca}^{2+}\) is present in sarcoplasm
4 Till polymerization of myosin head is going on
Locomotion and Movement

238299 Myosin head separates from actin when ::

1 ATP hydrolysis
2 When ATP attached to myosin head
3 When ATP releases from myosin head
4 When ATP releases from Act in
Locomotion and Movement

238300 When there is no change in muscle length during contraction, it is called:

1 isometric
2 isotonic
3 isostasis
4 refractory period
Locomotion and Movement

238301 Identify the correct order of stages in muscle contraction

1 Stimulus \(\rightarrow\) Release of acetyle choline \(\rightarrow\) Release of \(\mathrm{Ca}^{2+}\) ions \(\rightarrow\) Excitation of triad System \(\rightarrow\) sliding of thin filaments \(\rightarrow\) Zmembranes brought closer
2 Stimulus \(\rightarrow\) Release of acetylcholine \(\rightarrow\) Excitation of triad System \(\rightarrow\) Release of \(\mathrm{Ca}^{2+}\) ions \(\rightarrow\) formation of cross bridges \(\rightarrow\) sliding of thin filaments \(\rightarrow\) Z-membranes brought closer
3 Stimulus \(\rightarrow\) Excitation of triad System \(\rightarrow\) Release of acetylcholine \(\rightarrow\) Release of \(\mathrm{Ca} 2+\) ions \(\rightarrow\) sliding of thin filaments \(\rightarrow\) formation of cross bridges \(\rightarrow Z\)-membranes brought closer
