Glucose Fermentation by Clostridium Spp

question 9

Multiple Choice

Glucose fermentation by Clostridium spp.produce ATP only when acetate and butyrate are produced.Why do these organisms produce acetone and butanol after strong initial activity of generating ATP with acetate and butyrate byproducts?

• A) Acetate and butyrate accumulation creates a deadly acidic environment, which acetone and butanol do not.
• B) Acetate and butyrate are no longer needed for biosynthetic pathways.
• C) Acetone and butanol serve as better sources for NAD(P)⁺ reduction.
• D) Acetone and butanol production is favored for stability to store intracellular carbon sources for potential nutrient poor conditions.
