Any substance that has enhanced reactivity, or altered properties in the presence of light is said to be photoreactive. For example, a photovoltaic cell enables sunlight to be processed into usable electricity by exciting outer shell electrons on some metals. Photoreactive substances can either be natural, such as chlorophyll, or entirely man-made in the case of a photovoltaic cell.
Answer:
The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.
The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.
