Which statement about the Golgi apparatus is INCORRECT

Question

BlackTom AI · Accepted Answer

Here’s how to break down each statement about the Golgi apparatus and evaluate its accuracy.
Option 1: The Golgi apparatus is involved in export of cell contents. This is correct. The Golgi participates in processing, sorting, and shipping proteins and lipids out of the cell via vesicles that fuse with the plasma membrane or other destinations in the cell.
Option 2: Ribosomes can attach to the Golgi apparatus for protein synthesis. This is incorrect. Ribosomes are the sites of protein synthesis and are typically attached to the endoplasmic reticulum (rough ER) or are free-floating in the cytosol. They are notAttachment points for the Golgi; the Golgi processes and packages proteins that have been synthesized elsewhere, mainly in association with the ER.
Option 3: Proteins can be biochemically altered within the Golgi apparatus. This is correct. The Golgi is a hub for post-translational modifications such as glycosylation, sulfation, and trimming of carbohydrate chains, among other modifications, which tailor proteins for their final destinations.
Option 4: The Golgi regularly gives and receives membrane from the cell membrane. This is correct. The Golgi participates in membrane trafficking, sending vesicles to and receiving vesicles from various membranes, including the plasma membrane, contributing to membrane composition and distribution.
Overall, the second statement stands out as not aligning with the known roles of the Golgi; ribosomes do not attach to the Golgi for protein synthesis, whereas the other statements accurately reflect Golgi functions.
