Course description and aims

The aim is to understand biological functions through interpretation of elementary process of biological phenomenon as physicochemical reaction by learning of fundamental concepts, principles, and laws of physics. Students learn chemical equilibrium, electrical phenomenon, reaction kinetics, and biological process quantitatively from view points of statistical thermodynamics, and deepen their essential skill of consideration of physical phenomenon and chemical change. Taking concrete biological phenomena as the themes, students deepen their essential understanding. Through fundamental learning, ability of development and utilization of science and technology, that is ability of consideration for the applications in the bio science and engineering or clinical fields, is promoted.

Student learning outcomes

1) Understanding of chemical equilibrium, and explaining thermodynamically and statistical thermodynamically the reason why biological reactions occur.
2) Quantitative understanding of electrical phenomenon relating to transport of ion and electron, and explaining theory of solution and membrane transportation, battery, and biological energy.
3) Understanding of reaction kinetics, and construction of rate equation.
4) Discussion of biological reaction mechanism and reaction dynamics by rate equation.
5) Explaining enzymatic reaction and the inhibition as complex biochemical process by physical chemistry.
6) Explaining diffusion, ion transport, and electron membrane transport as elementary process of biological phenomenon by physical chemistry.

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.
