Nitrogenous Wastes
- Ammonia
- Extremely toxic; requires vast amounts of water to dilute
- Low cost of energy; mostly excreted by aquatic animals
- Urea
- Lower toxicity; NH4 + CO2 in the liver
- Energetically costly
- Uric Acid
- Much lower toxicity; NH4 bound in a heterocyclic compound
- High energetic cost; semi-water soluble - semi-solid paste
- Wastes resulting
from the
breakdown of
Proteins and Nucleic
Acids to form
nitrogenous wastes
and amino acids
