Protein diverse functions and locations

organismal, ecological and evolutionary levels continue to develop rapidly. Increasingly, biologists need to confront organised complexity, of which living systems are the paramount example. Both spontaneous emergence of order and the maintenance of stability in complex systems in the face of highly variable environments need to be researched further. Complex structures are generated and maintained through energy fl ux, placing energy fl ow as one of the most important components of biological systems. In addition, diversity, whether of molecular form at the cellular level or organismal variation at the ecological level, is another crucial characteristic of biological systems.
