The common waste product generated by skeletal muscle is

The most common waste product generated by the skeletal system is creatine which serves as the energy storage that is necessary for muscle contraction. Elevated level of this that can be found in the urine can cause muscle dystrophy to the person.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
