Question

If the small intestine secretes 12 g of bile salts into the duodenum in one day and the ileum reabsorbs 95% of them, how many grams of bile salts must the liver synthesize de novo each day to make up for unrecovered bile salts? Show the calculation.

Accepted Answer

0.6 g/day

Answer

6 g/day

Answer

0 g/day because all bile salts are recycled perfectly and no new synthesis is needed

Answer

12 g/day because the liver must make as much as is secreted even with reabsorption efficiencies.
