The heavy meromyosin (HMM) component, i.e the head and short arm projects outwards at regular distance and angle form each other from the surface of a polymerised myosin filament and is known as
1 Cross arm
2 Motor unit
3 Cross bridge
4 Neuromuscular junction
Explanation:
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 polymerised myosin filament and is known as cross arm.

ATPase of the muscle is located in
1 Actinin
2 Troponin
3 Myosin
4 Actin
Explanation:
ATPase of the muscle is located in myosin. The globular head is an active ATPase enzyme and has binding sites for ATP and active sites for actin.

Select the option which identifies any one part (A-C) of the following diagram and gives its correct description.
1 A: Troponin - A complex protein distributed at regular intervals on the actin
2 B: Troponin - Two filaments run close to the F-actins
3 C: G-actin - A polymer of monomeric F-actins
4 A: Myosin - ATP binds to it
Explanation:
Troponin is a complex protein distributed at regular intervals on the actin molecule, masking its active sites.

Choose the incorrect pair.
1 Globular head of meromyosin - Active ATPase enzyme
2 Thin elastic membrane holding -M-line thick filaments in A-band
3 Dark bands - Anisotropic band
4 Each actin (thin) filament is made of two 'F' (filamentous) actins
Explanation:
The thin filaments are firmly attached to the ' Z ' line. The thick filaments in the ' A ' band are also held together in the middle of this band by a thin fibrous membrane called ' M ' line.
