Question

myosin filaments are close to how many times thick as an actin filament​

Answer 1

Answer:

Myosin filaments are close to 3 times as thick as actin filaments.

Explanation:

Muscle fibres can contain up to a few thousand myofibrils, which make up about 85% of the content of a muscle fibre. Myosin filaments are close to 3 times as thick as actin filaments.

Answer 2

Answer:

about 8nm

Explanation:

Myosin is thick filament in muscle fibres and it is also called Anisotropic band or dark band.

Myosin filament is 15nm thick and filament is composed of myosin head, arm, neck . Myosin head attaches to myosin binding site of actin.

Actin is a thin filament also called Isotropic band or light band. Actin filament is 8nm thick and is composed of two chains of F actin.
