Four types of proteins make up myofilaments

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.
