Biochemistry

- In this chapter, it is crucial for the student to have an overview of metabolism by clearly visualizing all metabolic pathways, the connections between them, the pathways favored by the organism based on its needs, and especially the anatomical localization of each pathway. After this overview, we will discuss the enzymatic reactions of each pathway.

• We will first examine the four stages of cellular respiration:

  • Glycolysis

  • Decarboxylation of pyruvate

  • Krebs Cycle

  • Oxidative Phosphorylation

Next, we will explore the reactions of gluconeogenesis, the synthesis and degradation of glycogen, and finally, the pentose phosphate pathway.
