Cell Ribosome

Ribosomes are like tiny factories in the cell. They make proteins that perform all sorts of functions for the cell's operation.

Where are ribosomes located inside the cell?

Ribosomes are either located in the liquid inside the cell called the cytoplasm or attached to the membrane. They can be found in both prokaryote (bacteria) and eukaryote (animals and plants) cells.

Organelle

Ribosomes are a type of organelle. Organelles are structures that perform specific functions for the cell. The ribosome's job is to make proteins. Other organelles include the nucleus and the mitochondria.

Ribosome Structure

The ribosome has two main components called the large subunit and the small subunit. These two units come together when the ribosome is ready to make a new protein. Both of the subunits consist of strands of RNA and various proteins. The "S" in the subunit names is a unit of measure and stands for the Svedberg unit.


Protein Synthesis

The main job of the ribosome is to make proteins for the cell. There can be hundreds of proteins that need to be made for the cell, so the ribosome needs specific instructions on how to make each protein. These instructions come from the nucleus in the form of messenger RNA. Messenger RNA contain specific codes that act like a recipe to tell the ribosome how to make the protein.

There are two main steps in making proteins: transcription and translation. The ribosome does the translation step. You can go here to learn more about proteins.

Translation

Translation is the process of taking the instructions from the messenger RNA and turning it into a protein. Here are the steps the ribosome takes to make the protein: Interesting Facts about the Ribosome Activities
