Please choose the Incorrect Statement

SPC 32a)

MERCK 1999:

Phase I reactions form a new or modified functional group or a cleavage (oxidation, reduction, hydrolysis). These are non synthetic - the most important are cytochrome P450 isoenzymes (CYPs) that transfer electrons and catalyze oxidation.

Phase II reactions are synthetic - involving conjugation with an endogenous compound forming metabolites more polar and readily excreted by the kidneys and liver in urine and bile.

SPC 32b)

BLOCK 2012:
"...The epithelium of olfactory mucosa has high activity and expression of cytochrome P450 (CYP) isoforms including CYP1A2, 2A, 2B, 2E, and 2G (Longo 2000, Livertoux 1996, Voight 1993). These phase I enzymes catalyze the biotransformation of ambient air pollutants such as polycyclic aromatic hydrocarbons, semi-quinones and quinones into toxic metabolites, such as mutagenic epoxide or reactive oxygen species...

...phase II enzymes in the nasal cavity epithelium, such as UFP-glucuronosyltransferase, epoxide hydrolase, sulfotransferases, and glutathione-S-transferases (Bond 1988), function to detoxify the reactive metabolites formed by CYP dependent activities. Thus, the appropriate balance of phase I and II enzymes in the epithelium of olfactory mucosa may provide a first line of defence for the brain, limiting axonal transport of ambient air pollutants and toxic metabolites from the olfactory nerve cells to the olfactory bulb..."

SPC 32c)
Sensory receptor activation and alveolar macrophage involvement in damaged airway epithelium due to ACA PM - changes in the innate inflammatory immune system (Hogg 2009, Abbas 2007) - can't result in release of mediators - neuropeptides, cytokines, chemokines, and growth factors (Dantoft 2014, Maes 2012, Deering-Rice 2011, Hazari 2011, Costa 2010, Deluca 2010, Taylor-Clark 2010, Caceres 2009, Anand 2008, Bessac 2008), Nassenstein 2008, Bautista 2006, Inoue 2005, Kobayashi 2005, Veronesi 2001), increase in circulating leukocytes, production of acute phase proteins Hiraiwa 2014, 2013, Hogg 2009, Goto 2004, Mukae 2001), nitric oxide overproduction (Maes 2012, Deluca 2010, Calderon-Garciduenas 2008), and dysfunction of Phase I and II xenobiotic and antioxidant enzymes in a systemic condition of severe oxidative stress (Deluca 2010, Liptrott 2009, Oslund 2008, Chun 2002, Sterner-Kock 1999, Tinel 1999, Tanabe 1996, Tapner 1996, Nadin 1995, Stadler 1994, Khatsenko 1993).
