What metabolic advantage do cells have in storing the elemental sulfur byproduct from sulfide oxidation?
A. The cells avoid producing transport energy waste to secrete the sulfur.
B. The byproduct serves as an electron reserve for subsequent oxidation.
C. Sulfur decreases the intracellular acidification for non-acid-tolerant sulfide oxidizers.
D. The byproduct can be used for other biosynthetic pathways that use sulfur, such as Rieske Fe-S proteins.
