What is the final digestive process for nucleosides?

Explanation:
Nucleosides are not absorbed intact in the gut; they are hydrolyzed in the intestinal lumen to purine and pyrimidine bases and a sugar. The bases are then taken up across the enterocyte membrane by active transport, becoming available for nucleotide salvage or further metabolism. This makes the cleavage into bases with active transport the best description of the final digestive step for nucleosides.
