Understanding Cellular Respiration

The video explains the importance of ATP as the energy currency in cells, detailing the process of aerobic cellular respiration in eukaryotic cells. It covers glycolysis, the Krebs Cycle, and the electron transport chain, highlighting the role of mitochondria. The variability in ATP production is discussed, along with the significance of ATP in cellular functions and the impact of mitochondrial diseases.
