Which cell organelle containing millions of membrane-bound ribosomes is involved in the production, folding, quality control and dispatch of certain proteins?
Rough endoplasmic reticulum
The correct answer is Rough endoplasmic reticulum.
Disulfide Bond Formation: Enzymes in the RER lumen catalyze the formation of disulfide bonds, which help stabilize protein structure. Quality Control: The RER has mechanisms to ensure that only properly folded and assembled proteins are allowed to leave. Misfolded proteins are retained in the RER and may be targeted for degradation by the proteasome (ER-associated degradation or ERAD). Once processed and deemed correctly folded, proteins are transported from the RER to the Golgi apparatus via transport vesicles.
