The green fluorescent protein (GFP) is a type of protein widely used in molecular biology laboratories because this protein can be used to detect the expression of proteins and to identify cellular structures. This protein displays green fluorescence when it is excited by blue light and, in the last years, many variants of the GFP protein have been developed. The altered GFP proteins react to distinct wavelengths of light, thereby emitting light to different colors. The mutants forms of the GFP protein are produced by genome engineering techniques that generate modifications capable of altering the folding of the normal GFP protein.
Scientists are concerns about the loss of species because the loss of one species can set off a chain reaction that cause other species to die out and affect out food chain.
I believe it is they are reactants because they’re present before the reaction. O2 and glucose are reactants in the cellular respiration process. The product is ATP
