The course improves the knowledge of students about the metabolism of biomolecules. The course starts by demonstration the role of enzymes in catalyzing metabolic reactions and explaining the production of ATP during the respiratory chain. The students will learn how the carbohydrates, lipids, and protein in the diet are digested, absorbed, and catabolized for production of energy or for production of important building blocks for the human body. Also, they will study the metabolic integration between different pathways during the starve-feed cycle.
