The heavy meromyosin (HMM) component, i.e the head and short arm projects outwards at regular distance and angle from each other from the surface of a polymerised myosin filament and is known as 

Select the total number of false statement from the following (i) The globular head is an active ATPase enzyme and has binding sites for ATP and active sites for Myosin. (ii) Each Myosin filament is also a polymerized protein (iii) Many monomeric proteins celled Meromyosins constitute one thick filament. (iv) Each meromyosin has two important parts, a globular head with a short arm and a tail, the former being called the heavy meromyosin (HMA) and the latter, the light meromysin (LMN). (v) The HMM component, i.e., the head and short arm projects outwards at regular distance and angle from each other from the surface of a polymerized myosin filament and is known as cross arm (a) 5 (b) 4 (c) 2 (d)1

The figure showsn tow parallel equipotential surface A and B kept at a small distance 'r' a part from each other. A point chang of Q coumomb is taken from the surface A to B. The amount of net work done will be

Which of the following statements about the molecular arrangement of actin and mysin In myofibre is/are incorrect ? (i) Each actin (thin filament) is made of 2F (filamentous) actins. (ii) F-actin is the polymer of G (globular) actin. (iii) 2F0actins are twisted into a helix. (iv) Two strands of tropomyosin (protein) lie in the grooves of F-actin. (v) Troponin molecules (complex proteins) are distributed at regular intervals on the tropomyosin. (vi) Troponin forms the head of the myosin molecule. (vii) The myosin is a polymerised protein.
