ABSTRACT
Biochemical and chemical reactions are vital to living organisms. For example, complex molecules such as starch or proteins have to be broken down into simpler molecules. These simpler molecules can then either be consumed in further biochemical reactions to produce energy or used as building blocks to construct the complex molecules organisms need for growth, repair, and reproduction. In fact, all the processes of metabolism involve biochemical and chemical reactions, and so knowledge of how such reactions work is necessary for the understanding of living organisms.
