The ATP Cycle: Energy Transformation and Cellular Processes

The video explains the role of ATP as the energy currency of the cell, detailing the ATP cycle where ATP is synthesized from ADP through phosphorylation and broken down via hydrolysis to release energy. The phosphoanhydride bond between oxygen and phosphorous is highlighted as the key energy source. The cycle involves both endothermic and exothermic reactions, with a net energy gain. The video concludes with a preview of further discussions on ATP's energy release and instability.
