Answer
Answer: A ✓ checked by 4AB · confidence high
Answer: I–F, II–C, III–D, IV–A.
Explanation
Answer: I–F, II–C, III–D, IV–A — Oxyhemocyanin transports O₂. Carbonic anhydrase hydrates CO₂ to H₂CO₃/HCO₃⁻. Cytochrome P450 oxygenates substrates, e.g. epoxidises alkenes. Carboxypeptidase A hydrolyses the C-terminal peptide bond.
