Write the differences between: Actin and Myosin
|1||Found in both A and I bands||Found only in A band of sarcomere|
|2||Thinner (0.005 mm) but shorter (2- 2.6 mm) than myosin filaments||Thicker (0.01 mm) but longer (4.5 mm) than actin filaments|
|3||Cross bridges absent,hence have smooth surface||Cross bridges present, hence have rough surface|
|4||More numerous than myosin filaments, six of them surround each myosin filament||Fewer than actin filaments|
|5||Free at one end and are joined to Z-line by other end||Freeat both the ends|
|6||Consist of 3 protiens: actin, tropomysin and troponin||Consist of 2 proteins : myosin and meromyosin|
|7||Slide into H-zone during muscle contraction||Do not slide during muscle contraction|
