WebAug 11, 2024 · In contrast, bound ribosomes produce proteins that are released into the ER lumen (the fluid space inside the ER) before moving from the rough ER to the smooth ER (3, at right). When a free ribosome synthesizes a protein, it releases that protein directly into the cytoplasm. What happens at the rough endoplasmic reticulum and the Golgi ... WebAlmost 60% of the endoplasmic reticulum has ribosomes attached to its cytoplasmic surface and is known as the RER. The remaining 40% constitutes the SER, which lacks a coating of ribosomes.
