Question

A. Students should be able to describe breakdown of excess proteins to form urea for excretion.
B. Students often confuse the breakdown of excess proteins with the breakdown of carbohydrates or fats, leading to incorrect explanations about urea formation.
C. It is not correct that students should be able to describe breakdown of excess proteins to form urea for excretion.
D. The idea only requires memorising the topic title for Respiration.

Answer

In this question, Students should be able to describe breakdown of excess proteins to form urea for excretion. is correct It stays aligned to the exact wording and meaning of the objective.

Explanation

In AQA-style practice, the correct answer must match the objective closely and use the science rather than filler wording. That is why Students should be able to describe breakdown of excess proteins to form urea for excretion. is the best option here. Linking the idea to large molecules made up of amino acids that are essential for the structure, function, and regulation of the body's tissues and organs keeps the explanation specific.

Common mistake

Misunderstanding Protein Breakdown

Students often confuse the breakdown of excess proteins with the breakdown of carbohydrates or fats, leading to incorrect explanations about urea formation.

Focus on the specific process of deamination, where amino acids are converted to urea in the liver, and ensure to differentiate this from carbohydrate and fat metabolism.
