Document Summary

Bchm 3114 learning goals: metabolism and free energy: recognize that oxidation of reduced carbon is the source of chemical energy in humans. Explain why fatty acids provide more chemical energy per carbon atom than carbohydrates. The more reduced a group is, the more energy it provides. Energy is generated by the oxidation of carbohydrates or lipids, therefore the more reduced a group is, the more room there is for oxidation. Fatty acids are more reduced than carbohydrates, therefore more electrons are liberated for electron transport to occur. Fats need more oxygen for each carbon atom, which produces more energy: indicate the order in which energy sources are utilized in humans. Spontaneous , non-spontaneous , and equilibrium appropriately in a thermodynamic context. Delta g is the difference in the energy between reactants and products. The reaction is spontaneous when the sign is (-) and it is non-spontaneous when the sign is (+).
