At the end of this reaction, 1 molecule of 'NADP+', 1 molecule of 'Dextrorphan', 1 molecule of 'Formaldehyde', and 1 molecule of 'H2O' are present.<br><br> This reaction takes place in the 'smooth endoplasmic reticulum' and is mediated by the 'oxygen binding activity' of 'Cytochrome P450 2D6 '.<br> | lld:biopax3 |
