Some ribosomes are attached to the endoplasmic reticulum and form rough ER. They are known as bound or attached ribosomes. Both ribosomes are involved in synthesizing proteins that are necessary to use within the cell and that are necessary to secrete outside the cell or use in lysosomes. Free ribosomes freely move around the cell while bound ribosomes cannot change their locations. You can download PDF version of this article and use it for offline purposes as per citation notes.

Ask a New Question. This environment prohibits proteins with sulfur in the form of a disulfide bond from being made by the detached ribosomes. The types of proteins made by the two different ribosome types differ in other ways beyond disulfide bonds.
Detached ribosomes figure heavily in cellular metabolism and generate enzymes that release the energy from glucose molecules. Attached ribosomes make proteins targeted for specific purposes outside the cell, such as digestive enzymes used in the gut.
They also produce hormones and certain cell membrane proteins that act as surface receptors. Much of the output from ribosomes travels to another cell organelle, the Golgi bodies, which sort and package the proteins for particular uses.
