Enzymes are biological catalysts which increase reaction rates by lowering the activation energies of substrates. A substrate is a reactant that interacts with the enzyme. The enzyme and substrate can be viewed as the recently discovered "induced fit model"‚ which suggests enzymes are flexible and dynamic

The Tyndall effect‚ also known as Tyndall scattering‚ is light scattering by particles in a colloid or particles in a fine suspension. It is named after the 19th-century physicist John Tyndall. It is similar to Rayleigh scattering‚ in that the intensity of the scattered light depends on the fourth power of the frequency‚ so blue light is scattered much more strongly than red light. An example in everyday life is the blue colour sometimes seen in the smoke emitted by motorcycles‚ in particular two-stroke machines
