Question

Which of the following is not a function of the smooth endoplasmic reticulum in the liver?
A) It removes toxic wastes.
B) It contains calcium ions which are released to cause contraction.
C) It releases glucose into the blood.
D) All of these choices are functions of the smooth endoplasmic reticulum in the liver.

Accepted Answer

The smooth endoplasmic reticulum (SER) in the liver is involved in various metabolic processes including detoxification, lipid synthesis, and carbohydrate metabolism. It does not contain calcium ions for muscle contraction; that function is more associated with the sarcoplasmic reticulum in muscle cells.
