An engine takes in chemical energy and gives mechanical energy out.so it does a transformation of energy to carry out work.a living cell is similiar to an engine as it takes oxygen and converts it into carbon dioxide to get energy.but a cell is different from an engine as respiration takes place in it.also because a cell can repair itself but an engine cant repair itself.a cell is an living entity but an engine is not a living entity
