Title: Smooth ER
Post by: chang190 on Nov 4, 2010
Determine whether the following statements about the Smooth ER are true or false.

1. Phospholipid precursors are water soluble and found in the cytosol.
2. The smooth ER membrane is continuous with the Golgi apparatus membrane.
3.they can be removed by the body.
4.There is an equal concentration of enzymes responsible for lipid synthesis in both leaflets of the smooth ER membrane.

ah, sorry the third option should be read as:

Enzymes in the smooth ER detoxify water-soluble compounds into lipid-soluble compounds, so they can be removed by the body.

2. The smooth ER membrane is continuous with the Golgi apparatus membrane.
3. Enzymes in the smooth ER detoxify water-soluble compounds into lipid-soluble compounds, so they can be removed by the body. [It's actually the opposite, hydroxyl groups are added so that they become water soluble.]
4. There is an equal concentration of enzymes responsible for lipid synthesis in both leaflets of the smooth ER membrane.

Bolded answers are true
