Cellular Respiration
Learning Time: 4-12 hours
Content: Cellular respiration is the process by which cells produce energy (ATP) by reacting organic molecules with oxygen. This topic covers glycolysis, the Krebs cycle, the electron transport chain, and anaerobic respiration (fermentation). The TYT focuses on the basic stages of aerobic respiration, while the AYT focuses on energy efficiency and alternative pathways. The current 2025 curriculum also includes mitochondrial diseases and metabolic adaptations associated with sports performance. Learning this topic is critical for energy metabolism and cellular functions.
