Arrange the following events of muscle contraction in the squence :-(I) Generate an action potential in the sarcolemma(II) Form a cross bridge (III) Release a neurotransmitter (Acetylcholine)(IV) Release of calcium ions (V) Pulls the attached actin filaments towards the centre of ''A'' band. (VI) Remove the masking of active sites for myosin The correct option is :- A I → II → III → IV → V → VI B III → IV → I → II → VI → V     C III → I → IV → II → V → VI D III → I → IV → VI → II → V

During contraction of muscles following do not take place :-(a) Shortening of sarcomere            (b) Shortening of A-band(c) Shortening of actin    (d) Shortening of myosin

Which of the following happens as actin and myosin filaments slide past each other during muscle contraction?

he following is a list of the events that occur during a muscle contraction.1. Myosin cross-bridges bind to the actin.2. The free myosin head splits ATP.3. Calcium ion is released from the sarcoplasmic reticulum.4. The myosin head pivots toward the center of the sarcomere.5. Calcium ion binds to troponin.6. The myosin head binds an ATP molecule and detaches from the actin.The correct sequence of these events isQuestion 10Select one:a.3, 5, 1, 2, 4, 6.b.1, 3, 5, 4, 6, 2.c.1, 4, 6, 2, 3, 5.d.3, 5, 1, 4, 6, 2.e.5, 1, 4, 6, 2, 3.

Which event does not happen during muscle contraction ?Actin filaments move towards H-zone Decreased length of myosin filament Decreased length of sarcomereLength of A-band remains unchanged.
