WebMar 17, 2024 · There are two types of myofilaments: thin and thick. The thin filaments are mainly made up of three proteins: F-actin, tropomyosin, and troponin. The thick filaments, for their part, are made up solely of another protein known as myosin II. WebFeb 11, 2024 · Explanation: Ultrastructure of sarcomere contains two types of myofilaments i.e actin (thin) & myosin (thick) filaments. Thin Filament : Thin filament is 7 − 8nm in diameter. Thin filament extends the entire length of I-band. It is composed of three proteins that are: (a) Actin → The thin filaments are composed chiefly of actin proteins.

WebMyosin myofilaments (thick filaments) [1] Structure . Contain ∼ 250 myosin molecules; Muscle myosin molecules (myosin II) [2] Various isoforms occur in different muscle types and determine the speed of contraction; Consist of two heavy and two light protein chains; Domains. Head: has both an actin and ATP binding site (which also has ATPase ... WebAt 40-nm intervals along the thin myofilaments, tropomyosin molecules are attached to troponin complexes. In the troponin complexes, there are three proteins: troponin I, troponin T, and troponin C. Troponin I anchors the complex to the thin myofilament; troponin T attaches to the tropomyosin molecules, and troponin C binds calcium. hindustan aeronautics limited ofs
