Match the chemical reaction to the visual effect of the product/biochemical test description 1. This assay's color change relies on an initial reduction reaction resulting in a black precipitate if the organisms is "positive" 2. The visual production of gas from this reaction indicates this organism can break down toxic byproducts of aerobic respiration. 3. This assay relies on a pH indicator (phenol red) for a color change. An organism that was "positive" for the certain enzyme in this assay, would result in a pink color change. 4. If an organism was incubated in simple broth containing a phenol red pH indicator and a sugar source, and the broth turned yellow following bacterial growth, that would be evidence of this reaction occurring. 5. The reaction representing this assay, works by producing a red colored product upon addition of a reagent, which tells us the organism possesses the enzyme required to break down a particular amino acid.
