Document Summary

Biol 112 lecture 5 energy & thermodynamics. Metabolism = the chemical processes that occur within a living organism in order to maintain life. It can be divided into 2 types of aciviies: Anabolic: anabolic reacions link simple molecules together to make complex molecules: these are energy-storing reacions and they also require energy. Catabolic: catabolic reacions break down complex molecules into simpler ones: these reacions release energy. Cells must constantly acquire energy from their environment. Potenial energy kineic energy heat released. Ex. raised brick has the potenial to do work, has pe due to pull of energy falling brick has ke (due to moion) heat is released when brick hits the loor. Thermodynamics in biology = the quanitaive study of the energy transducions that occur in and between living organisms, structures, and cells; and of the nature funcion of the chemical processes underlying these transducions. 1st law: during any conversion of energy, the total iniial energy = total inal energy .
