A)starch and cellulose.
B)triglycerides and steroids.
C)proteins and nucleic acids.
D)phospholipids and glycolipids.

Nitrogenous wastes, such as urea and ammonia, are produced mostly from the breakdown of proteins and nucleic acids during catabolism. Starch, cellulose, triglycerides, and other compounds do not contain nitrogen, so they do not produce nitrogenous wastes.
