How does e coli get energy?

E. coli bacteria obtain energy primarily through a process called cellular respiration, where they metabolize nutrients such as glucose. In aerobic conditions, they use oxygen to break down glucose, producing ATP (adenosine triphosphate) as the energy currency. In anaerobic conditions, E. coli can switch to fermentation or anaerobic respiration, utilizing alternative electron acceptors to generate energy. Additionally, E. coli can also utilize other organic compounds and substances for energy, demonstrating metabolic flexibility.
