what is a protein that is the main component of the thick filaments in muscle fibers and is responsible for muscle contraction?\n○ actin\n○ myosin\n○ atp\n○ dna

Answer

Answer:

B. myosin

Brief Explanation:

Myosin is the main protein in thick filaments of muscle fibers and drives muscle contraction. Actin is in thin - filaments. ATP is an energy - carrier molecule, not a filament component. DNA is the genetic material, not related to muscle filament structure for contraction.
