Low energy bulbs produce too limited a spectrum of light for full activity. As the temperature increased past 40 degrees the enzymes have become denatured, and therefore the substrates no longer bind to the active sites.

Immobilized enzymes are enzymes which may be attached to each other, to insoluble materials, or enclosed in a membrane or gel. As enzymes have an optimum temperature to function at which is in the region of degrees, this has resulted in the rate also ommobilised at 40 degrees.
