Question

where is the site of lipid synthesis? golgi apparatus nucleus smooth endoplasmic reticulum (er) peroxisome

Explanation:

The smooth endoplasmic reticulum (ER) is the main site for lipid synthesis in cells. The Golgi apparatus is mainly involved in modifying, sorting and packaging proteins and lipids. The nucleus contains genetic material and is the control - center of the cell. Peroxisomes are involved in various metabolic reactions including the breakdown of fatty acids, not major lipid synthesis.
