Cells obtain energy primarily through the process of cellular respiration, where glucose is broken down in the presence of oxygen to produce ATP (adenosine triphosphate), the primary energy currency of the cell. This process occurs in three main stages: glycolysis, the Krebs cycle, and the electron transport chain. Additionally, some cells can generate energy through anaerobic respiration or fermentation when oxygen is scarce. Overall, efficient energy production is crucial for maintaining cellular functions and supporting life processes.
