Answer 2

                                HMM AND LMM

• ‘Light-meromyosin’ (LMM) is thick portion or the “backbone portion” of the molecule, which is also said as tail part in a molecule.
• It intertwines the tail part of nearby myosin molecules forming a dense filament. Heavy-meromyosin (HMM) comprises of two different subfragments namely S-1 and S-2.
• These both LMM and HMM are a part of meromyosin. Each meromyosin comprises of a globular head with short arm referred as HMM and a tail named Light meromyosin LMM.
• The active ATPase enzyme is the head and binds with the sites for “ATP and active sites” for actin.
