Document Summary

Different type of chemical reactions in a cell: all of them are called metabolism. Anabolic joins simple molecules to make more complex ones (ex: making a polypeptide or a dna molecule). Catabolic break down polymers into monomers. (ex: cutting up a protein into is original amino acids). Everything that we do can be described as energy conversion. Ex: at the beginning, before release, the brick has potential energy which is then transformed to kinetic energy (cid:449)hile it s falling and then it con(cid:448)erts to heat. The energy content does not drive energy conversion. At the beginning you have the same amount of energy than you have at the end. Same for atoms: at the beginning you have the same amount of atoms than at the end. The drive of energy to become evenly distributed or dispersed. A cup of hot coffee is essentially energy highly localized in a narrow environment.
