Document Summary

Assessment at the end of the chapter (pg. Complexity with precise spatial organization: ability to respond to the environment, reproduction, evolve. There are components found both in living and nonliving organisms. But each of them must obey certain chemical rules: thermodynamics energy can be neither created nor destroyed. **biological systems cannot break the law of thermodynamics.

Carbon based molecules: molecules necessary for every living thing to store energy, use energy and the instructions for making that energy: proteins structural, enzymatic, signaling, structure is different, but the chemical formula is the same.
