What organelle makes lipids and steroids

It contains more than 151 different polypeptides , and has a very high protein-to-phospholipid ratio (more than 3:1 by weight, which is about 1 protein for 15 phospholipids). The inner membrane is home to around 1/5 of the total protein in a mitochondrion. [13] In addition, the inner membrane is rich in an unusual phospholipid, cardiolipin . This phospholipid was originally discovered in cow hearts in 1942, and is usually characteristic of mitochondrial and bacterial plasma membranes. [43] Cardiolipin contains four fatty acids rather than two, and may help to make the inner membrane impermeable. [13] Unlike the outer membrane, the inner membrane doesn't contain porins, and is highly impermeable to all molecules. Almost all ions and molecules require special membrane transporters to enter or exit the matrix. Proteins are ferried into the matrix via the translocase of the inner membrane (TIM) complex or via Oxa1. [40] In addition, there is a membrane potential across the inner membrane, formed by the action of the enzymes of the electron transport chain .

The cell is highly organized with many functional units or organelles. Most of these units are limited by one or more membranes. To perform the function of the organelle, the membrane is specialized in that it contains specific proteins and lipid components that enable it to perform its unique roles for that cell or organelle.  In essence membranes are essential for the integrity and function of the cell.
