Does protein make actin and myosin?
Actin and myosin are proteins. Protein is a broad category of molecules.
What are thick myofilaments of muscles called?
Actin. Myosin are the thin ones.... it's actually the reverseThe thin filaments are composed primarily by the protein Actin.The thick filaments are composed primarily of the protein Myosin.
What protein makes up the thick myofilament?
The thick myofilaments are formed from a protein called myosin.
The larger of the two filaments forming a cross-bridge is made of a protein called?
Myosin
Is it true that thick filaments are made of a protein called actin?
false, it's made of myosin
What is the name of the regulatory protein?
myosin and actin
Myofibrils are constructed of overlapping strands of protein polymers?
Actin and Myosin. A conglomeration of actin fibrils and myosin filaments form a myofibril body called a sarcomere.
What is composed of myosin protein?
thick filaments
What are the names of protein filaments in a muscle fiber?
