Answer 1

Adenine and guanine are purines, and the final excretory product of purine metabolism in human is uric acid. Firstly, adenine and guanine are converted to xanthine. Enzyme xanthine oxidase exclusively found in liver and small intestines) then converts xanthine to uric acid.

Answer 2

As we know both bases are Purines, hence they would be secreted as uric acid.

Moreover guanine is the waste product of spiders and penguins.
