During muscle contraction, the length of all the following gets reduced except?
(A) H-Zone
(B) A-Band
(C) I-Band
(D) Sarcomere

During muscle contraction, all of the following occur except

During muscular contraction, which of the following events occur? (i) H-zone disappears (ii) A-band widens (iii) I-band reduces in width (iv) Width of A-is unaffected (v) M-line and Z-lne come closer (v) M-line and Z-line come closer

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

From B_(2)H_(6) , all the following can be prepared except

Which of the following component is absent in visceral muscles? (A) Myosin (B)Actin (C) Sarcosome (D) Sarcomere

Which of the following component is absent in visceral muscles? (A) Myosin (B) Actin (C) Sarcosome (D) Sarcomere

Assertion : In muscle contraction, length of both A-bands and I-bands decrease. Reason : Both myosin of A-band and actin of I-bands are contractile proteins and decrease in size during muscle contraction.

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

Statements A-bands of the muscle are dark and contain myosin I-band are the light bands and contain actin During muscle contraction the A-band contracts The part between the two Z-lines is called as sarcomere The central part of thin filament, not over-lapped by thick filament is called H-zone of the above statements.
