Top 10 Commonly Confused Words in Metabolic Biochemistry

Top 10 Commonly Confused Words in Metabolic Biochemistry 1. Glycolysis vs. Gluconeogenesis Glycolysis and gluconeogenesis are both metabolic pathways involved in glucose metabolism. However, they have opposite functions. Glycolysis is the breakdown of glucose to produce energy, while gluconeogenesis is the synthesis of glucose from non-carbohydrate sources. Remember, 'lysis' means breakdown, and 'neo' means new, which can help differentiate the two. 2. Anabolism vs. Catabolism Anabolism and catabolism are two fundamental processes in metabolism. Anabolism refers to the building of complex molecules from simpler ones, while catabolism is the breakdown of complex molecules into simpler ones. Think of anabolism as 'building up' and catabolism as 'breaking down'. These processes are interconnected and crucial for maintaining cellular homeostasis. 3. Oxidation vs. Reduction Oxidation and reduction are often abbreviated as 'redox' reactions. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. A helpful mnemonic is 'LEO says GER' - Loss of Electrons is Oxidation, Gain of Electrons is Reduction. These reactions play a vital role in energy transfer within cells.
