During the muscular contraction which of the following events occur? (a) H zone disappers (b) A band widens (c) T band reduces in width (d) Z line attached to actins are pulled inwards (e) Arachidonic acid has 16 carbon atoms. choose the correct answer from the options given below

During muscle contraction (a) A band remains of length same (b) I band increases (c) H zone and M line disappear (d) I band increases (e) Membrane of Krause comes closer (f) Sarcomere lengthens

During muscle contraction (a) A band remains of length same (b) O band increases (c) H zone and M line disappear (d) I band increases € Membrane of Krause comes closer (f) Sarcomere lengthens

In which state does an atom emit (i) line spectrum, (ii) band spectrum ?

Consder the diagram showing muscle structure below. Identify the events that occur during skeletal muscle contraction. I. I-band shortens II. A-band shortens III. H-zone shortens IV. Sarcomere contracts V. ATP changes to ADP and Pi Choose the option incorrect event(s).

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.
