Lectures

Biological Molecules 6: An introduction to molecular biology and evolution

How evolution can be studied at the molecular level.

Biological Energy 3: Light, energy and upstream processes

An introduction to the chemical and physical processes involved in photosynthesis

Biological Energy 4: Molecular energy transfer and photobiology

The energy-transfer process in photosynthesis.

Biological Energy 5: Electron transfer theory

An explanation of the essential process of electron transfer in photosynthesis.

Supplementary lecture: Chemical reaction kinetics and equilibrium

This lecture provides chemistry background to lectures in biological physics. It can either be presented in a single session or be drawn upon to provide supplementary material as and when needed for the biological physics lectures.

Regulatory networks 1: Introduction to regulatory networks

The binding of proteins and DNA can control cell behaviour by turning genes on and off.

Regulatory networks 2: The physics of biological regulation

Some simple models can tell us a lot about how regulatory networks work.

Regulatory networks 3: Biochemical noise

Cells with identical genes in identical environments can behave differently. This can be explained in terms of biochemical noise.

Thermodynamics 1: Statistical mechanics

Statistical mechanics (or statistical thermodynamics) provides methods for circulating the probability that a system with a very large number of components will be found in a given state, and hence predicting its most likely state.

Thermodynamics 2: Brownian motion

The movement of particles in a fluid can be described in terms of the average behaviour of a large number of particles in random motion.

Thermodynamics 3: Amphiphile aggregation - critical micelle concentration

The formation of micelles and bilayers can be described in terms of statistical thermodynamic functions, such as chemical potential and free energy.

Thermodynamics 4: Micelle geometry

The size and shape of a micelle are determined by the geometry of its constituent molecules and by the forces that act between them.

Thermodynamics 5: Lipid bilayers

Biomembrane deformation, governed by curvature elasticity, is important in many biological processes.

Thermodynamics 6: Fluctuating membranes

The thermally driven roughness of membranes can be analysed statistically
