Question

In humans waste product of nucleotide metabolism is excreted as

Answer 1

molecular oxygen, the oxident in both reaction, to reduced to H2O2 which is decomposed to H2O and O2 by catalase .Uric acid loses a proton physiological pH to form urate

Answer 2

Nucleotides are the building blocks of nucleic acids. When nucleic acid is broken down into nucleotide it is further broken down by two intestinal brush border enzymes such as nucleosidase and phosphatase into smaller units such as nitrogenous bases sugar and phosphate groups.

These products are then carried by carrier molecules across the vilus epithelium and enters bloodstream and follows the standard pattern of excretion.
