Given the following diagram, describe what happens electronically between these two molecules.
Myosin Myofilaments
Protein filaments in muscle cells that function with actin filaments to cause muscle contraction through their sliding mechanism.
Actin Myofilaments
Thin filaments in muscle cells that, along with myosin filaments, contribute to muscle contraction.
I Band
Area between the ends of two adjacent myosin myofilaments within a myofibril; Z disk divides the I band into two equal parts.
M Line
Line in the center of the H zone made of delicate filaments that holds the myosin myofilaments in place in the sarcomere of muscle fibers.
