Document Summary
>>>>>the chemistry of life is organized into metabolic pathways. --metabolism the totality of an organism"s chemical reactions. Metabollic pathways- begins with a specific molecule, which is then altered in a series of defined steps resulting in a specific product. --catabolism release energy by breaking down complex molecules into simpler compounds. --anabolism consume energy to build complicated molecules from simpler ones. --potential energy energy that an object posses because of its location or structure. --kinetic energy energy associated with relative motion of objects. >>>>>energy transfers are subject to the laws of thermodynamics (see fig 8. 3) The study of the energy transformation that occur in a collection of matter. --first law of thermodynamics the energy of the universe is constant: energy can be transferred or transformed but not created or destroyed. --second law of thermodynamics during every energy transformation some energy becomes unable to do work. --entropy (s) a measure of disorder or randomness.
