Answer:

C

Explanation:

Ammonia is toxic to the body. Animals that live in water excrete their waste in ammonia (aqueous) form because it is less toxic when diluted. However, land animals need to convert the ammonia to a less toxic product such as urea before excretion. Ammonia is formed through deamination of amino acid.

ANSWER:

The correct option is C: Ammonia. Ammonia is a toxic and waste compound that is of concern.

EXPLANATION:

Proteins contain nitrogen and during the catabolism of nitrogen containing compounds, hydrogen, carbon and oxygen are extracted and stored in the "form of fats and carbohydrates "by the body.

  • The excess nitrogen however gets excreted from the body. The nitrogenous wastes form "toxic ammonia" which raises the level of pH of the body fluids.
  • The toxic ammonia must be converted to "uric acid or urea" which is a non-toxic form.
