Go through the following statements  During muscle contraction, the width of A-band remains constant while I-band shortens.   During muscle contraction, the `Ca^(2+)` released from the SR bind to the troponin component of thin filament  The process of muscle contraction is faster in smooth muscle as they have a well developed sarcoplasmic reticulum.   The red muscle fibres have abundant mitochondria, low glycogen and poorly formed sarcoplasmic reticulum.
