What examiners said

Comprehensive responses • Most candidates identified the small molecule that glycogen is made from. Limited responses • The common incorrect response given was glycerol.

— Examiner report, February/March 2026, 0654/32 Q1(a)(ii) (Cambridge)

Amino acids were commonly given as the smaller molecules that make up proteins. A minority of candidates misinterpreted the question and gave the elements that each example was composed of. The smaller molecules that starch is made from proved the most troublesome.

— Examiner report, February/March 2024, 0654/42 Q4(c) (Cambridge)

Few candidates were able to answer this question correctly. The only smaller molecule correctly identified was amino acids from which proteins are made.
