The sequence list of types of materials in order from least conductive to the most conductive is: insulator, semiconductor, conductor and superconductor. Conductors are materials where electric current can flow freely; whereas, in insulators, electric current cannot. Examples of conductors are metals and water. Examples of insulators are plastics, papers and rubbers.
Lysosomes use a degenerative enzyme to eliminate un necessary materials from the cell and recycle parts that can be re used, much like a recycling centers eliminate waste from cities and find ways to reuse it.
