Question

In which organelle synthesis of lipid molecules takes place?
(a) Smooth endoplasmic reticulum
(b) Rough endoplasmic reticulum
(c) Golgi apparatus
(d) Plastids

Answer 1

Hint: A membranous organelle present in most eukaryotic cells is a smooth endoplasmic reticulum (smooth ER). It is a branch of the endoplasmic reticulum endomembrane scheme. The synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism within the cell of calcium ions are its main functions. The smooth ER is characterised by the absence of membrane-bound ribosomes from the other parts of the endoplasmic reticulum.

Complete answer:
The rough endoplasmic reticulum synthesises lipid molecules in a cell.
Rough endoplasmic reticulum has ribosomes over its surface and proteins that are very helpful for an organism are synthesised. They have a rough surface and are also known as rough endoplasmic reticulum.
A lipid is a macro biomolecule which is soluble in nonpolar solvents in biology and biochemistry. Typically non-polar solvents are hydrocarbons used to remove other naturally occurring lipid hydrocarbon compounds, including fatty acids, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, and phospholipids, which do not dissolve in water.

Additional information:
In essence, the endoplasmic reticulum (ER) is the eukaryotic cell's transport mechanism and has many other essential functions, such as protein folding. The rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER) are a type of organelle composed of two subunits. In most eukaryotic cells, the endoplasmic reticulum forms an interconnected network of flattened, membrane-enclosed sacs in the SER known as cisternae (in the RER) and tubular structures. With the external nuclear membrane, the membranes of the ER are continuous. In red blood cells or spermatozoa, the endoplasmic reticulum is not contained.
The Golgi apparatus is an organelle that is present in most eukaryotic cells, also known as the Golgi complex, Golgi body, or simply the Golgi. It bundles proteins into membrane-bound vesicles inside the cell as part of the endomembrane system in the cytoplasm before the vesicles are sent to their destination. At the intersection of the secretory, lysosomal, and endocytic pathways, it lives.

So, the correct answer is ‘Smooth endoplasmic reticulum’.

Note:
From what scientists believe were tiny prokaryotic organisms living inside other prokaryotic organisms, plastids emerged. Until finally becoming part of the cell, they assume that these organelles, along with mitochondria, began a symbiotic or mutually beneficial relationship with the larger prokaryotic cell.
