Biophysics I: Molecular Binding and Energy Extraction

This lecture covers the concepts of molecular binding and energy extraction in biophysics, focusing on the role of ATP as a fuel source. The instructor explains the process of ATP hydrolysis and its significance in providing energy for cellular functions, such as protein transformations and metabolic reactions. The lecture also delves into the Smoluchowski problem, discussing the isotropy of molecular binding and the steady state of complex formation. Furthermore, the Hill equation and Langmuir isotherm are introduced to understand the equilibrium between ATP, ADP, and phosphate. Overall, the lecture provides insights into the fundamental principles governing molecular interactions and energy transfer in biological systems.
