Assertion :- In the contraction of muscle myosin slide on actin filament. Reason : Actin become constant & myosin shows rotational movement proved by sliding filament theory :

In the skeletal muscle, the interaction between actin and myosin filaments is triggered by

The order in contraction in muscle in (a)Generation of action potential in muscle fibres (b)Release of neuro transmitter at motor c) Formation of cross linkages between actin and myosin (d) Release of Ca^(2+) and binding to troponin C

3. Locomotion And Movement_The Myofilaments Actin And Myosin

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.
