The Smooth ER
The smooth endoplasmic reticulum (ER) is the organelle that carries out these functions. It is responsible for synthesizing lipids such as phospholipids and steroids, as well as detoxifying various harmful substances. Unlike the rough ER, the smooth ER does not have attached ribosomes on its surface.
Ribosomes
The endoplasmic reticulum (ER) is continuous with the nucleus and is responsible for synthesizing lipids. It has two regions: the rough ER, which is studded with ribosomes and synthesizes both membrane proteins and lipids, and the smooth ER, which lacks ribosomes and synthesizes lipids, including phospholipids and steroids.
ribosomes
Yes. Endoplasmic reticulum is found in all eukaryote cells.
In basic terms a ribosome is an organelle that synthesizes proteins by combining sequences of 20 amino acids.
The organelle that anchors ribosomes is the Rough Endoplasmic Reticulum (ER). The Rough ER and ribosomes work very closely together. The rough Endoplasmic Reticulum is also the site of protein synthesis. The Smooth ER synthesizes lipids.
Rough Endoplasmic Reticulum synthesizes proteins, and the Golgi Apparatus modifies and packages them.
The nucleolus is the organelle inside the nucleus of eukaryotic cells where ribosomes are produced. It synthesizes ribosomal RNA (rRNA) and assembles ribosomal subunits. These ribosomal subunits then exit the nucleolus to combine in the cytoplasm and form functional ribosomes.
The smooth endoplasmic reticulum functions in the synthesis of lipids, including steroid hormones and detoxification of drugs and harmful substances. It lacks ribosomes on its surface, which distinguishes it from the rough endoplasmic reticulum involved in protein synthesis.
The organelle that assists in the production of ribosomes is the nucleolus, which is found within the nucleus of eukaryotic cells. The nucleolus synthesizes ribosomal RNA (rRNA) and combines it with proteins to form the subunits of ribosomes. These ribosomal subunits are then transported to the cytoplasm, where they assemble to create functional ribosomes that facilitate protein synthesis.
The organelle responsible for protein production inside the cell is the ribosome. Ribosomes are either free in the cytoplasm or attached to the endoplasmic reticulum, and they are essential for translating messenger RNA into proteins.
