The Smooth Endoplasmic Reticulum aids to detoxify drugs and poisons in the liver.
-
True
-
False
Correct Answer
A. FalseExplanation
The Smooth Endoplasmic Reticulum does play a role in detoxification, but it is mainly involved in lipid and steroid synthesis, as well as the metabolism of carbohydrates. The liver contains a large amount of Smooth Endoplasmic Reticulum, which helps with these functions, but it is not specifically responsible for detoxifying drugs and poisons. This task is primarily carried out by the liver's microsomes and other enzymes.
