In resting stage, binding sites for myosin on actin filaments are masked by

Read the following statements and select the correct option : I. In the skeletal muscles fibre, large number of myofilaments are arranged in the sarcoplasmic . II. The central part of an anisotropic band where the only thick , filament is present and thin filament is absent is called 'A' band. III. In the resting state , a tropomyosin protein masks the active b binding sites for myosin on the active filaments . IV. The junction between a motor neuron and the sarcolemma of the muscle fibres is called motor-end plate.
