IB Biology HL B1.1.4 Form and Function of Monosaccharides Questions

Practise IB Biology HL B1.1.4 by comparing ribose and glucose, linking glucose solubility and stability to its role, and distinguishing alpha- and beta-glucose at carbon 1.

Exam points

Identify ribose as a pentose and glucose as a hexose from their structural diagrams.
Explain how glucose's solubility, transportability and stability suit it as a respiratory substrate.
Distinguish alpha- and beta-glucose at carbon 1 and link each form to different polysaccharides.

[Maximum number: 3]
