(a)I-F; II-C; III-D; IV-A
(b)I-E; II-C; III-A; IV-F
(c)I-F; II-B; III-C; IV-A
(d)1-E; II-D; III-C; IV-A
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
Oxyhemocyanin transports O₂. Carbonic anhydrase hydrates CO₂ to H₂CO₃. P450 oxygenates (epoxidises) alkenes. Carboxypeptidase A cleaves the C-terminal peptide bond (a).
