Biochemical Processes and Reactions

The video tutorial explains metabolism as the sum of all chemical reactions in an organism, divided into anabolism and catabolism. Anabolism involves building molecules and requires energy, while catabolism breaks down molecules and releases energy. Examples include glucose synthesis and sucrose breakdown. Practice problems help identify processes as anabolic or catabolic, such as cellular respiration and photosynthesis.
