Assertion. On receiving action potential...

Assertion. On receiving action potential via T-tubules, the sarcoplasmic reticulum releases `Ca^(++) ` into the sarcoplasm.
Reason. `Ca^(++)` uncover the active site of actin myofilament, allowing a meromyosin head to join this site.

Assertion:Action potential passes into the muscle fibre by way T-tubules and Z-line and sarcoplasmic reticulum release calcium ions into the sarcoplasm. Reason:The released calcium results in sliding of thin myofilaments over the thick myofilaments of the myofibrils, leading to contraction of the muscle

Assertion: on stimulation, a muscle cell releases calcium ions (Ca^(2+)) from sarcoplasmic reticulum. Reason: By reacting with a protien complex, Ca^(2+) uncover active sites on the actin filaments.

Which of the following statements given below are true with reference to muscle contraction. I. Neurotransmitter acetycholine is released as nerve impulse reaches the end of axon and binds to receptor sites of motor end plate. II. Action potential passes from motor end plate over sarcoplasmic and then into the T-tubules and sarcoplasmic reticulum. III. Calcium ion are released into the sarcoplasm bind to troponin, causing a change in its shape and position. IV. Myosin cross bridges are able to bind to exposed active sites of actin. Choose the correct option.

Arrange the following events of muscle contraction in the sequence : (i) Generate an action potential in the sarcolemma (ii) Form a cross bridge (iii) Release a neurotransmitter (Acetylcholine) (iv) Release of calcium ions in sarcoplasm (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 :-

The steps involved in the mechanism of muscle contraction are given below. Arrange the steps in proper sequential order and select the correct option. I. Release of calcium ions in the sarcoplasm. II. Signal sent by the CNS via a motor neuron. III. Binding of calcium with a subunit of troponin on actin filaments. IV. Generation of the action potential in the sarcolemma. V. Binding of myosin head to the exposed active sites on actin to form a cross-bridge. VI. Inward pulling of ‘Z’ line attached to actin causing shortening of the sarcomere. VII. Pulling of the attached actin filaments towards the centre of 'A' band. VIII. Release of neurotransmitter acetylcholine and generation of the action potential in the sarcolemma.

Assertion : Ca^(2+) plays important role in the muscle contraction. Reason : Ca^(2+) Combines with troponin chain, displacing tropomyosin allowing the myosin head part to combine with actin to from actomyosin complex .

Assertion : - Ca^(++) play an important role in the muscle contraction. Reason :- Calcium bind with a subunit of troponin on actin filaments and thereby remove the masking of active sites for myosin.

Following is given a randomly arranged list of events that occur at neuromuscluar junction to trigger mucle contraction. (i) Receptor sites on sarcolemma Nerve impulse (iii) Release of Ca^(+2) from sarcoplasmic reticulum (iv) The neurotransmitter acetylcholine is released (v) Sarcomere shorten (vi) Synaptic cleft (vii) Spread of impulses over sarcolemmna on T-tubules Which of the following gives the correct sequence of these steps?
