Quick explanation
Describe (HT only) deamination in the liver as removal of the amino group from excess amino acids to produce ammonia
- This point belongs to Hormonal coordination in humans, especially Maintaining water and nitrogen balance in the body (biology only).
- You need to be able to describe (HT only) deamination in the liver as removal of the amino group from excess amino acids to produce ammonia.
- The key ideas to know are ammonia, HT only, and deamination.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters
This objective helps connect Maintaining water and nitrogen balance in the body (biology only) to exam-style questions, flashcards, and revision notes for Hormonal coordination in humans.
Quick student answer
How does (HT only) deamination in the liver work?
Direct answer
In Biology, this page helps you answer questions about (HT only) deamination in the liver within Hormonal coordination in humans. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are deamination and ammonia.
Key terms
- deamination: The process in the liver where the amino group is removed from excess amino acids, resulting in the production of ammonia.
- ammonia: A toxic substance produced during deamination that must be converted into urea for safe excretion from the body.
Common trap
Misunderstanding Deamination: Remember that deamination specifically refers to the removal of the amino group from excess amino acids in the liver, not during digestion.
