What is a Ribosome?

The organelles that are usually attached to rough endoplasmic reticulum (ER) and produce enzymes and other protein compounds are called ribosomes.

To understand why ribosomes are attached to rough ER and their role, let's break it down:

1. Structure of Rough Endoplasmic Reticulum: Rough ER is a network of interconnected membranous tubules or sacs called cisternae. These cisternae have ribosomes attached to their outer surface, which gives the rough appearance under a microscope.

2. Ribosomes: Ribosomes are small, spherical organelles made up of ribosomal RNA (rRNA) and protein molecules. They are responsible for protein synthesis, which involves assembling amino acids to form polypeptide chains according to the instructions provided by messenger RNA (mRNA).

3. Role of Ribosomes on Rough ER: Ribosomes attached to the rough ER play a crucial role in producing proteins that are destined for various functions within the cell or for export outside the cell. These proteins include enzymes, receptors, transport proteins, or structural components of the cell.

4. Co-translational Protein Synthesis: Ribosomes on rough ER allow for co-translational protein synthesis, where the growing polypeptide chain is directly translocated into the ER as it is being synthesized. This localization within the ER allows for proper folding, modification, and processing of newly synthesized proteins.

In summary, ribosomes are attached to rough endoplasmic reticulum and produce enzymes and other protein compounds through their role in co-translational protein synthesis, ensuring proper protein folding and modification within the ER.
