Lipid molecules in the cell are sythesized by
(a) smooth endoplasmic reticulum
(b) rough endoplasmic reticulum
(c) golgi apparatus
(d) plastids
Explanation: The Smooth endoplasmic reticulum helps manufacture fat molecules, or lipids, important for cell function. The smooth endoplasmic reticulum (SER) has functions such as it synthesizes lipids, phospholipids, and steroids. Cells which secrete these products, such as those in the testes, ovaries and sebaceous glands have an abundance of smooth endoplasmic reticulum. Hence, (a) is the correct option.
