Sulfolobus species produce __________; as a result, their immediate environment has a pH __________.
A) H₂SO₄; as low as 2
B) H3PO4; as low as 3
C) HCl; of 1
D) CH3COOH; of 4
E) HCOOH; of 3

Question

Quizplus · Accepted Answer

Sulfolobus species are acidophile archaea that produce sulfuric acid (H₂SO₄) as a byproduct of their metabolism, which results in an extremely low pH environment. The pH around Sulfolobus can reach as low as 2, making them highly adapted to acidic environments. This pH level is caused by the oxidation of elemental sulfur, which is a process unique to Sulfolobus species.
