Ribosomes are where protein synthesis occurs.
Ribosomes are an organelle that can be found floating around in your cell's cytoplasm, or attached to the rough endoplasmic reticulum.
What is Protein Synthesis?
Proteins are extremely important because they regulate what can enter and exit the cell. While some small molecules can pass through the cells membranes, most charged molecules, like sodium ions, and large molecules like glucose enter and exit your cell through transport proteins. Without ribosomes, your cells would be unable to make the proteins that form essential parts of the cell, like the transport proteins on the cell membrane, and you would almost certainly be dead! Good thing we have those ribosomes!
