Assertion: Mechanism of muscle contraction is expalained by sliding-filaments theory. Reason: Contraction of muscle fibre takes place by the sliding of thick filaments over the thin filaments.

Assertion:Skeletal muscles contraction is due to shortening of sarcomere Reason:Sarcomere is the functional unit of skeletal muscles

Read the following statements regarding muscle contraction (i) One ATP utillised for making and breaking of the cross bridge. (ii) The sarcomere lies between 2 Z-lines (iii) Troponin blocks the active sites in resting stage (iv) Ca^(++) ions help in unmasking active sites on HMM Choose the correct option
