Detailed explanation-1: -Proteins can be translocated into the ER either during their synthesis on membrane-bound ribosomes (cotranslational translocation) or after their translation has been completed on free ribosomes in the cytosol (posttranslational translocation).
Detailed explanation-2: -The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins. Sometimes, when those proteins are made improperly, the proteins stay within the endoplasmic reticulum.
Detailed explanation-3: -Due to all the ribosomes found on the RER, secretory proteins are synthesized here.
Detailed explanation-4: -Transport vesicles are able to move molecules between locations inside the cell. For example, transport vesicles move proteins from the rough endoplasmic reticulum to the Golgi apparatus. Lysosomes are vesicles that are formed by the Golgi apparatus.
