Which statement is false concerning the Golgi apparatus? Select one: a. Vesicles coming from the rough endoplasmic reticulum enter the cis face of the Golgi apparatus b. The Golgi apparatus consists of a stack of flattened membrane sacks called cisternae c. Proteins are post-translationally modified in the Golgi. This can include proteolytic cleavage or glycosylation of proteins destined to be localized on the membrane (like the proteins that give rise to ABO blood types!).
