Prokaryotic cells generate energy primarily through cellular respiration and fermentation. In aerobic conditions, they use the process of cellular respiration to convert glucose into ATP (adenosine triphosphate) via glycolysis, the Krebs cycle, and the electron transport chain, often utilizing oxygen as the final electron acceptor. In anaerobic conditions, some prokaryotes can perform fermentation, breaking down glucose without oxygen to produce ATP along with byproducts like lactic acid or ethanol. Additionally, certain prokaryotes can harness energy from inorganic substances through processes like chemosynthesis.
