Summary Introduction
To explain: The forms of
Concept introduction: Mechanical energy involves two forms – potential energy and kinetic energy. Potential energy of an object corresponds to the energy by vitue of its position. Kinetic energy corresponds to the energy by virtue of its motion.

- With regard to muscle contraction, which of the following is an INCORRECT statement with regard to the interactions of filaments that occur in the sarcomere? A. When muscles are relaxed tropomyosin blocks binding sites on actin subunits, which keeps cross-bridges from forming. B. The myosin heads conduct a power stroke motion to slide when bound to actin, to move the "thin" filaments towards the center of the sarcomere. C. During contraction, actin subunits are removed from the ends of the "thin" filaments to shorten actin polymers, thus reducing the length of the sarcomere. D.
