Chemical Reactions and Energy Microbial life can exist only where molecules and cells remain organized, and energy is needed by  all microorganisms to maintain organization. Every activity taking place in microbial cells involves both a shift of energy and a measurable loss of  energy. Although the second law of thermodynamics says that energy cannot be created or  destroyed, but only transferred within a system, unfortunately, the transfers of energy in living  systems are never completely efficient. For this reason, considerably more energy must be taken into  the system than is necessary to simply carry out the actions of microbial life. In microorganisms, most chemical compounds neither combine with one another automatically nor  break apart automatically. A spark called the  energy of activation  is needed. The activation energy
