Document Summary

We"re made up of ~100 trillion (1014) cells. Cells contain trillions of molecules, containing tens of thousands of atoms. Molecules and cells are arranged in structures, i. e. , organs, bones, and skin. Molecules can synthesized on very short notice, i. e. , adrenalin or insulin. It is a protein made up of 51 amino acids. Those amino acids are all connected in exactly the correct order and folded into exactly the molecular shape needed for its function in the metabolism of glucose. (note: hydrogen atoms are not shown for simplicity. Carbon atoms are black, oxygen atoms are red and nitrogen atoms are blue. ) The answer lies in the coupling of reactions. Your body extracts gibbs free energy from the foods we eat. Consider the single nutrient glucose (also known as dextrose or blood sugar). A large quantity of gibbs free energy can. When glucose is burned in the presence of air, all the gibbs free energy is release as thermal energy.
