Bound vs free ribosome
WebDec 21, 1978 · Our results indicate that in yeast cells the two types of ribosomes are in different functional states --the membrane-bound ribosomes are active in pro- tein synthesis, the free ribosomes are in a state of latent rest, obviously representing a reserve pool which allows the cell to increase its protein syn- thesis rate rapidly. WebNov 13, 2015 · Some of the proteins synthesized by ribosomes are for the cell's own internal use, especially those that are produced by free ribosomes.
