Question
- A. Students should be able to describe how qualitative reagents can be used to test for starch, glucose and proteins.
- B. Students often confuse the reagents used to test for starch, glucose, and proteins, leading to incorrect conclusions about the presence of these substances.
- C. It is not correct that students should be able to describe how qualitative reagents can be used to test for starch, glucose and proteins.
- D. The idea only requires memorising the topic title for Photosynthesis.
Answer
In this question, Students should be able to describe how qualitative reagents can be used to test for starch, glucose and proteins. 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 how qualitative reagents can be used to test for starch, glucose and proteins. is the best option here. Linking the idea to substances used to detect the presence of specific biomolecules, such as starch and glucose, through color changes or other observable reactions keeps the explanation specific.
Common mistake
Misidentifying Reagents
Students often confuse the reagents used to test for starch, glucose, and proteins, leading to incorrect conclusions about the presence of these substances.
Review the specific reagents for each test: iodine solution for starch, Benedict's solution for glucose, and Biuret reagent for proteins. Practice using each reagent correctly in a practical setting.
