The following entails a brief discussion of the biochemistry module of learning. Biochemistry deals with the complex chemical reactions that take place in the living systems, focusing on the structure and function of the biomolecules. The cellular metabolism and product synthesis are the components of biochemistry. Enzymes and co-enzymes play a crucial role in biochemical reactions. ATP is the universal energy currency of the living cells (Kee et al. 2013). Glycolysis, TCA cycle and Krebs cycle are examples of biochemical pathways.
