What molecules (proteins) allow all of the biochemical reactions that occur in our bodies to proceed at a temperature that is compatible with life?  2. In other words, how is it that all kinds of metabolic activities are occurring in our bodies without turning us into walking furnaces?  3. What specific mechanisms assist us in maintaining a core homeostasis? Give a detailed example. 4. What types of changes would we see in our bodies, life, and nature if hydrogen bonds did not exist? Detail one example of hydrogen bonding in nature, and what would happen if that bond did not exist.
