In the catalytic cycle of Cytochrome $\mathrm{P_{450}}$, the generation of $[(\text{porphyrin})^{+\bullet}\mathrm{Fe^{IV}(O)}]$ from $[(\text{porphyrin})\mathrm{Fe^{III}(OOH)}]$ involves
(a)One electron oxidation of $[(\text{porphyrin})\mathrm{Fe^{III}(OOH)}]$
(b)Formation of the intermediate $[(\text{porphyrin})\mathrm{Fe^{IV}(OH)}]$
(c)Homolytic O-O cleavage of $[(\text{porphyrin})\mathrm{Fe^{IV}(OOH)}]$
(d)Heterolytic O-O cleavage of $[(\text{porphyrin})\mathrm{Fe^{III}(OOH)}]$
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
Protonation of the Fe(III)–OOH (compound 0) leads to heterolytic O–O cleavage, releasing water and forming compound I, [(por•⁺)Fe(IV)=O] (d).
