The thermoacidophile Sulfolobus acidocaldarius lacks peptidoglycan, but still possesses a cell wall. Which of the following statements is likely to be an accurate description of this species?

Question

Quizplus · Accepted Answer

The thermoacidophile Sulfolobus acidocaldarius lacks peptidoglycan, which is a structural component found in the cell walls of bacteria. Hence, it is not a bacterium. Additionally, since it is an acidophile, the optimal pH of its enzymes will likely lie below pH 7, not above. However, it could inhabit hydrothermal springs, which are characterized by high temperatures and acidic conditions, making option C the correct choice. Option D is incorrect because Sulfolobus acidocaldarius is adapted to acidic environments rather than alkaline ones.
