IB Biology HL B1.2.12 Hl Globular Vs Fibrous Proteins Questions

Explore how compact globular proteins support catalysis, transport and signalling while fibrous proteins provide strength and support in IB Biology HL B1.2.12.

Exam points

Distinguish compact, often soluble globular proteins from long, often insoluble fibrous proteins using shape and solubility.
Relate globular form to catalysis, transport or signalling and fibrous form to tensile strength or structural support.
Use collagen, spider silk, haemoglobin or insulin as named examples of protein form and function.
