Metabolic Processes and Reactions

The video tutorial discusses the concept of metabolism, which encompasses all enzyme-catalyzed reactions in cells. It explains the roles of enzymes as biological catalysts and introduces the two types of metabolism: anabolism and catabolism. Anabolism involves building larger molecules from smaller ones through condensation, while catabolism breaks down larger molecules into smaller ones via hydrolysis. The tutorial provides a foundational understanding of these processes and their significance in molecular biology.
