Where are proteins and lipids produced in a cell?
The ER
The ER has a central role in lipid and protein biosynthesis. Its membrane is the site of production of all the transmembrane proteins and lipids for most of the cell’s organelles, including the ER itself, the Golgi apparatus, lysosomes, endosomes, secretory vesicles, and the plasma membrane.
Which organelle helps in the production of proteins?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
What is responsible for the production of lipids?
The organelle responsible for making lipids — which includes cholesterol, fatty acids and phospholipids — is the smooth endoplasmic reticulum. Not surprisingly then, the key structural feature of cells that synthesize lipids is an abundance of the SER. Hepatocytes, or liver cells, are an example of this type of cell.
What are the essential proteins and lipids manufactured?
Answer Expert Verified. The proteins and lipids, essential for building the cell membrane, are synthesized by the rough endoplasmic reticulum (RER). The ribosomes attached to the RER help in this process.
Where are lipids produced?
smooth endoplasmic reticulum
Lipids are made in the smooth endoplasmic reticulum (SER).
Which organelle helps detoxify the cell?
The smooth endoplasmic reticulum is also responsible for detoxifying the cell.
Which organelle is involved in the synthesis of lipids?
the ER
How Are Cell Membranes Synthesized? Membranes and their constituent proteins are assembled in the ER. This organelle contains the enzymes involved in lipid synthesis, and as lipids are manufactured in the ER, they are inserted into the organelle’s own membranes.
Which part of the cell produces lipids?
The smooth endoplasmic reticulum
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.
Which helps in lipid synthesis?
The endoplasmic reticulum (ER) is the main site for lipid synthesis.
What are the proteins and lipids?
Membrane proteins in a biological membrane are surrounded by a shell or annulus of ‘solvent’ lipid molecules. These lipid molecules in general interact rather non-specifically with the protein molecules, although a few ‘hot-spots’ may be present on the protein where anionic lipids bind with high affinity.
