This video introduces biochemistry, focusing on metabolism, which includes catabolism and anabolism. Metabolic pathways are controlled by enzymes in an aqueous environment. Catabolism breaks down large molecules, releasing energy, while anabolism builds up molecules, requiring energy. The energy from catabolic reactions fuels anabolic processes. Examples include glucose breakdown and protein synthesis. The video also covers biological molecules like lipids, proteins, vitamins, and carbohydrates, highlighting their diverse functions based on structure.
