Thermostable enzymes are able to keep their tertiary structure intact at high temperatures. Researchers investigating the primary structure of a thermostable enzyme discovered that it had: more charged amino acids; fewer polar amino acids that are uncharged; a greater number of hydrophobic amino acids than enzymes that are not thermostable. Which row gives the correct comparison between this thermostable enzyme and an enzyme that is not thermostable?
