Is it true that Fermentative organisms produce ATP through substrate-level phosphorylation rather than using an ATP synthase?

Yes. Fermentative organisms primarily produce their ATP through substrate-level phosphorylation rather than relying on membrane-bound ATP synthases.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked

The analysis

The claim is specific, empirical, and well-supported by fundamental microbiological literature indicating that fermentation pathways rely on substrate-level phosphorylation for ATP generation rather than oxidative/electron transport phosphorylation via ATP synthase.
