Summary Introduction
To review:
The fate of ammonia (formed when amino acids are broken down) in body of a fish and in body of a mammal.
Introduction:
Ammonia is the waste product that is to be removed from the body and since, it is very toxic it cannot be stored in the body of organism and diffusion has to be rapid and continuous. Ammonia is synthesized in all the organisms as nitrogenous wastes. It is formed when amino acids are broken down in the body.
