Biological Reactions and Energy

The video explores the essential roles of carbon and phosphorus in life, focusing on energy processes involving ATP. It explains catabolic and anabolic reactions, highlighting how energy is released or consumed. Dehydration synthesis is detailed as a process forming larger molecules like carbohydrates and proteins, while hydrolysis is described as breaking down molecules, crucial for digestion and energy release.
