Document Summary
In a closed system not matter enters or leaves. With the conversion of nutrients, we get desired, usable molecules and waste products that are excreted from the cell. The cell does not create energy but is converting energy. Gibbs free energy is the amount of energy that results at the end of the conversion aka the usable energy: thermodynamics refers to the free energy ( g, reactants have the covalent bonds that release energy, exergonic reactions. Energy is released as the reaction occurs. Reactants have more energy available than the products/reaction needs. Gibbs energy is the product energy minus the reactant energy, if g is negative, energy is released and the reaction is exergonic: endergonic reaction. Energy is absorbed as the reaction occurs. Reactants have less energy than the products/reaction needs. Gibbs energy is the product energy minus the reactant energy, if g is positive, energy is absorbed and the reaction is endergonic: energy coupling.
