In habitual alcohol drinkers liver gets damaged because of
A
accumulation of excess glycogen
B
accumulation of excess fat
C
excess detoxification
D
excess deamination
Answer
accumulation of excess fat
Explanation
Solution
In liver, alcohol is converted into a more toxic substance, acetaidehyde which is metabolized by cells for energy liver synthesises fat from alcohol and the extra fat decreases the production of enzymes and structural proteins.
Due to this, the liver becomes a storehouse of fat instead of a metaboliccentre. It causes fatty liver syndrome, leading to cirrhosis (replacement of liver cells by fibrous tissue).
