Comparison of samples from the liver of an alcoholic with samples from the liver of a non-drinker when examined by transmission electron microscopy would likely reveal that
A)the ultrastructure of the two livers is very similar.
B)the liver of the non-drinker has expansive rough ER compared to the alcoholic's liver.
C)the liver of the alcoholic has expansive smooth ER compared to the non-drinker's liver.
D)the liver of the alcoholic has substantially more lysosomes than the non-drinker's liver.

Question

Quizplus · Accepted Answer

Chronic alcohol consumption can lead to an increase in smooth endoplasmic reticulum (SER) in liver cells, which is responsible for detoxifying alcohol. This increase in SER can be observed through transmission electron microscopy. The expansive rough endoplasmic reticulum (RER) is not typically affected by alcohol consumption. There may be an increase in lysosomes in the liver of an alcoholic, but this is not the most significant difference as compared to non-drinkers.
