Choose the FALSE statement: The rough ER contains ribosomes. The ribosomes make proteins and the ER processes and sorts them on their way to the golgi apparatus. Cilia are tiny hair-like projections that can wave back and forth to move particles. In humans, flagella is only used to help move female eggs from the fallopian tube to the uterus. Because the rough endoplasmic reticulum and that smooth endoplasmic reticulum have different structures, they also have different functions.

The first statement is true. The rough endoplasmic reticulum (RER) does contain ribosomes, which synthesize proteins. The RER then processes and sorts these proteins before they are transported to the Golgi apparatus. The second statement is also true. Cilia are Show more…

Which one of the following statements is false? A. rough endoplasmic reticulum (RER) does not contain ribosomes on its surface and is involved in phospholipid synthesis B. an organelle is a specialized structure with specific cellular functions C. the secretory pathway explains the movement of secretory proteins from the endoplasmic reticulum to the Golgi apparatus D. the signal sequence is cleaved by signal peptidase and released into the ER lumen E. signal recognition particles are composed of proteins and RNA that binds to signal sequences and targets polypeptide chains to the endoplasmic reticulum
