Biochemical Processes and Reactions

This video introduces biochemistry, focusing on metabolism, anabolism, and catabolism. It explains the formation and breakdown of biopolymers through condensation and hydrolysis reactions, emphasizing the role of enzymes. The process of photosynthesis is detailed, highlighting its role in carbon neutrality. Key definitions and concepts are reinforced throughout.

What is the primary focus of biochemistry?

• The study of biological processes in non-living things

• The study of physical processes in living cells
