Cellular nitrogenous wastes (ammonia and urea), are a result of
A)beta oxidation of lipids
B)oxidative phosphorylation
C)catabolism of proteins
D)fermentation
E)anabolic production of amino acids

Question

Quizplus · Accepted Answer

Nitrogen is a component of amino acids, and catabolism of proteins releases nitrogenous wastes such as ammonia and urea. Beta oxidation of lipids, oxidative phosphorylation, and fermentation do not result in the production of nitrogenous wastes. Anabolic production of amino acids involves incorporating nitrogen into newly synthesized molecules, rather than releasing it.
