Course description and aims

Cells are composed of many kinds of biological molecules which mediate a variety of cellular activities. To enable the synthesis of the biological molecules as well as the cellular activities, animal cells synthesize adenosine triphosphate (ATP) by digesting glucose, fatty acids, and amino acids, and utilize the energy generated by ATP hydrolysis. This course will provide a comprehensive overview of energy metabolism (i.e., how cells synthesize ATP). Topics covered in this course include the following: glucose metabolism, fatty acid metabolism, amino acid metabolism, diseases caused by impaired energy metabolism, and regulation of energy metabolism. Mechanisms of homeostasis at a level of multicellular organisms will also be discussed.

This course aims at understanding the principle of energy production which is essential for all the biological activities.

Biochemistry II is designed to be taken with Biochemistry I and Molecular Biology I and II. Students are advised to enroll in all four courses in order to receive optimal instruction.

Student learning outcomes

By the end of this course, students will be able to:
1. Explain how cells synthesize ATP by metabolizing glucose, fatty acids, and amino acids.
2. Explain how energy metabolism is regulated depending on the conditions of each cell and organism.
3. Explain the roles of hormones and metabolites in homeostasis.

Keywords

Metabolism, Energy metabolism, Glucose metabolism, Amino acid metabolism, Nucleotide metabolism, Lipid metabolism, Homeostasis, Hormone

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Lectures are given by the Zoom broadcasting. When necessary, a summary of the previous lecture is given, followed by the main points of the day's lecture. During each lecture, questions may be given to find out if students have learned the material given.

Course schedule/Required learning

  Course schedule Required learning
Class 1 Glucose metabolism I: Glycolysis, fermentation Students must be able to explain how glucose is oxidized to pyruvic acid.
Class 2 Glucose metabolism II: Glyconeogenesis, glycogen metabolism. Students must be able to explain how glucose is synthesized from pyruvic acid.
Class 3 Citric acid cycle, alternative pathways. Students must be able to explain how pyruvic acid is catabolized in the presence of oxygen.
Class 4 Amino acid metabolism I: Catabolism and regulation of amino acids. Students must be able to explain how amino acids are catabolized.
Class 5 Amino acid metabolism II. Catabolism of individual amino acids Students must be able to explain the features in the catabolic pathways of individual amino acids.
Class 6 Amino acid metabolism III. Biosynthesis of amino acids Students must be able to explain how amino acids are synthesized.
Class 7 Respiratory chain, electron transfer system, oxidative phisphorylation. Students must be able to explain how ATP is synthesized in the respiratory chain.
Class 8 Nucleotide metabolism. Students must be able to explain how nucleotides are synthesized and catabolized.
Class 9 Lipid metabolism I: β-oxidation of fatty acids. Students must be able to explain how fatty acids are oxidized.
Class 10 Lipid metabolism II: Byiosynthesis of fatty acids. Students must be able to explain how fatty acids are synthesized.
Class 11 Lipid metabolism III. Digestion, absorption, and transort of lipids. Students must be able to explain how lipids are digested , absorpted, and transported in mammals.
Class 12 Regulation of metabolic reactions, and signaling molecules. Students must be able to explain how metabolites regulate metabolic flux.
Class 13 Regulation of glucose metabolism, hormones, and homeostasis. Students must be able to explain how glucose metabolism is regulated depending on the energy levels, and the role of hormones in the endocrine system..
Class 14 Review of classes 7 - 13. Students must be able to explain what they learned in classes 7 - 13.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Textbook(s)

Biochemistry, 4th edition (Donald Voet, Judith G. Voet, Tokyo Kagaku Dojin)

Reference books, course materials, etc.

Assessment criteria and methods

Students will be assessed on their ability to describe the biochemical processes given in the course and to utilize the knowledge for problem solving, and students' course scores are based on the reports etc. given in the lectures.
