During prolonged starvation, which mechanism explains the increased ammonia production in the digestive system?

A)Increased urea cycle activity
B)Bacterial fermentation of proteins
C)Enhanced gluconeogenesis in liver
D)Reduced intestinal bile secretion

💡 Explanation

Starvation leads to protein breakdown for energy, and bacterial fermentation in the gut uses these proteins, producing ammonia as a byproduct. This is because fermentation of proteins generates ammonia; therefore, bacterial fermentation increases ammonia levels, rather than urea cycle activity, gluconeogenesis, or reduced bile secretion.
