due to the genetic make-up and physiology of asians, the production of "clean-up" enzymes such as aldehyde dehydrogenase (aldh) is which may influence the low prevalence rates of alcoholism among asians.

There are choices for this question namely:

a. minimized 
b. maximized
c. optimized
d. neutralized

The correct answer is "minimized". Aldehyde dehydrogenase function to convert the toxic metabolite of alcohol which is aldehyde into a less toxic more excretable form of acetic acid. Asians have downregulated enzymes of aldehyde dehydrogenase which leads to more horrendous alcohol syndromes plus the embarrassing asian flush or the reddening of the face of asians after consuming alcohol.
