SUMMARY
Unicellular organisms, such as certain bacteria, can survive on a single type of substance, including simple fats or molecules like acetate, which serve as electron donors. These organisms can enter a dormant state, known as sporulation, allowing them to pause metabolic functions until favorable conditions arise. For example, Clostridium tetani can remain inactive in soil for extended periods before reactivating. Energy generation in these organisms relies on the breakdown of organic molecules, with nitrate serving as an electron acceptor in respiration, but not as a standalone energy source.
