Click and drag on elements in orderPlace the events of skeletal muscular contraction in chronological order.InstructionsDrag and drop application.Choice 1 of 6. Active sites exposed on G actin. toggle buttonActive sites exposed on G actin.Choice 2 of 6. ACh binds to the postsynaptic membrane stimulating an action potential in the sarcolemma. toggle buttonACh binds to the postsynaptic membrane stimulating an action potential in the sarcolemma.Choice 3 of 6. Myosin binds to actin and pulls actin towards center of sarcomere. toggle buttonMyosin binds to actin and pulls actin towards center of sarcomere.Choice 4 of 6. Action potential reaches presynaptic terminal, allow for the exocytosis of acetylcholine. toggle buttonAction potential reaches presynaptic terminal, allow for the exocytosis of acetylcholine.Choice 5 of 6. Calcium is released into sarcoplasm and binds to troponin. toggle buttonCalcium is released into sarcoplasm and binds to troponin.Choice 6 of 6. Action potential travels along sarcolemma and along transverse tubules. toggle buttonAction potential travels along sarcolemma and along transverse tubules.

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

What is the name for the linkage that forms between actin and myosin during muscle contraction?

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 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.

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.
