Question
- A. Fatty acids
- B. Nucleotides
- C. Amino acids
- D. Monosaccharides
Answer
The correct option is Amino acids.
Explanation
The correct option is Amino acids. Amino acids is correct because it directly supports the approved learning objective to different amino acids can be combined in the same chain to produce proteins. (HT only). This belongs to Polymerisation and naturally occurring polymers within Reactions of alkenes and alcohols (chemistry only), so the answer must use the correct organic chemistry context. The other options are incorrect when they confuse the organic family, formula type, reaction condition, product, or property being tested. Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.
Common mistake
Misunderstanding Protein Formation
Students often think that all amino acids are identical and can be combined in any order without affecting the protein's function.
Emphasize that the sequence and specific types of amino acids determine the protein's structure and function, highlighting the importance of the order in which they are combined.
