To test his hypothesis that the mutation had an effect on pyruvate’s ability to get inside the mitochondrion, he exposed normal yeast and mutant yeast to pyruvate for a period of them, before isolating and lysing the mitochondria of each set, and testing their mitochondrial extracts for levels of these products. If he had gotten the following result indicated in this image, what would this indicate?
