Energy is Conserved (The 1st law of thermodynamics) •  •  •  •  Total amount of energy is constant Living organisms cannot create energy from nothing Living organisms cannot destroy energy into nothing Living organisms may transform energy from one form to another –  Sunlight –  Nutrients (sugar, fat, etc), body –  Chemical synthesis –  Mechanical work –  Heat –  Gene/c informa/on transfer Biochemists use Enthalpy (not Energy) •  Most biological processes...
