Describe (HT only) deamination in the liver as removal of the amino group from excess amino acids to produce ammonia.

In the subtopic Maintaining water and nitrogen balance in the body (biology only), this learning objective focuses on describe (HT only) deamination in the liver as removal of the amino group from excess amino acids to produce ammonia. Within Hormonal coordination in humans, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include ammonia, deamination, and HT only. deamination means the process in the liver where the amino group is removed from excess amino acids, resulting in the production of ammonia. Avoid students often confuse deamination with the process of digestion, thinking it occurs in the stomach rather than the liver; instead remember that deamination specifically refers to the removal of the amino group from excess amino acids in the liver, not during digestion. For exam answers, focus on describing the deamination process clearly, emphasizing the removal of the amino group from excess amino acids and the production of ammonia.
