You do not consume alcoholic beverages, but your friend does, and he consumes these drinks regularly and in large amounts, If we could examine your liver cells and compare with your friend, would we see a difference in smooth ER and peroxisomes?
The drinking of alcohol brings about responses, specifically, stress responses. This then causes misfolded or unfolded protein to build up in the ER which is what leads to a number of problems with affected organs. With peroxisomes, when alcohol is consumed the number of it increases, as well as the surface density and volume. This is because it tries to detoxify the alcohol.
