Detailed explanation-1: -The endoplasmic reticulum (ER) is the main site for lipid synthesis.

Detailed explanation-2: -Lipids, fats are synthesised by the Smooth Endoplasmic Reticulum (SER) and the proteins are synthesised by rough endoplasmic reticulum (RER). The manufactured proteins and lipids are then sent to various places in the cell depending on need, using the ER.

Detailed explanation-3: -(ii) Smooth endoplasmic reticulum is the major site for synthesis of lipid.

Detailed explanation-4: -Lipids are made by enzymes embedded in the membrane of the SER. That’s because they have hydrophobic parts that don’t like the watery inside of the organelle. Meanwhile, the hydrophilic parts of the fats face into the cisternal space.

Detailed explanation-5: -The endoplasmic reticulum (ER) is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids. However, these two functions are performed in separate areas of the ER: the rough ER and the smooth ER.
