WitrynaSarcomeres are composed of long, fibrous proteins as filaments that slide past each other when a muscle contracts or relaxes. The costamere is a different component that connects the sarcomere to the sarcolemma. Two of the important proteins are myosin, which forms the thick filament, and actin, which forms the thin filament. Myosin has … Witryna10 wrz 2024 · What is made up of two types of protein filaments? The muscle cells are comprised of two kinds of filament; one comprised of actin and the other myosin (a type of protein). Normally, ATP binds to myosin, and when it is hydrolyzed to ADP, myosin binds to actin, making the microfilament slide. The sliding of numerous …
