Our cells contain a number of amazing molecular machines. The most important one is a turbine which is driven by the flow of protons - this is how most of our energy is generated. Another acts as the assembly plant for proteins, using information carried by mRNA from the DNA in the nucleus. There are tiny robots, which march up and down zip wires inside the cell to move materials around. Muscles are powered by a ratchet system of sliding filaments. Bacteria move around using a propeller which is a modified version of the energy turbine. I illustrate these amazing machines with colourful slides and animations.
