Eli5: what specific parts in the body define alcohol tolerance?

377 viewsBiologyOther

I wonder what defines alcohol tolerance in the biological level. Like because of this part or trait, I can drink x amount of bottles compared to the other guy that can only drink y amount od bottles.

Its said that you can develop alcohol tolerance, so I wonder which parts of the body change to reflect that.

The only trait that I know of currently is the size of the body since technically given the same amount of alcohol, a smaller body will be filled up more compared to a larger body.

Smooth Endoplasmic Reticulum in liver cells processes alcohol.

Studies (via biopsy) show that smooth ER increases as one’s drinking habit (and tolerance) increase.
