Q.1
Veterinary Biochemistry- ICAR JRF/SRF 2024 (Q.90)
MCQ (Single Correct) +4 −1
In phase one reaction of metabolism of xenobiotics, the reducing power is provided by
  • Phase I Xenobiotic Metabolism: Catalyzed by the microsomal Cytochrome P450 monooxygenase system in the smooth endoplasmic reticulum:
$$\text{RH} + \text{O}_2 + \text{NADPH} + \text{H}^+ \xrightarrow{\text{CYP450}} \text{ROH} + \text{H}_2\text{O} + \text{NADP}^+$$
  • Reducing Equivalents: The required electrons/reducing power are supplied by NADPH, which transfers electrons to cytochrome P450 via the flavoprotein NADPH-cytochrome P450 reductase (containing FAD and FMN).
  • Source of NADPH: Mainly generated via the pentose phosphate pathway (HMP shunt).

Correct option: (1) NADPH
